    Motherboard makers like Asus and MSI are releasing new BIOS updates that address a significant security vulnerability found in AMD’s CPUs. This problem is connected to the Trusted Platform Module (TPM) and has been officially designated as CVE-2025-2884. The flaw allows attackers with basic user access to possibly reach sensitive data or interfere with the TPM itself. Even though this vulnerability is viewed as medium risk, it stands out because it can be exploited more easily than many similar issues.

    Details of the Vulnerability

    The root of this security weakness lies in a coding mistake in the TPM 2.0 software, particularly in the CryptHmacSign() function. This flaw permits standard user applications to read more data than they should, which could expose as much as 65,535 bytes of sensitive information. As a result, attackers might take advantage of this issue to either access private data stored in the TPM or cause the module to fail, leading to a denial-of-service situation. The vulnerability is rated as medium severity (CVSS score of 6.6), but its risk is noteworthy due to how easy it is to exploit; it doesn’t need elevated kernel-level permissions, just regular user access.

    Affected Processor Models

    This flaw impacts a wide range of Ryzen processors, from desktop CPUs like Athlon 3000 “Dali” and Ryzen 3000 “Matisse” to Ryzen 9000 “Granite Ridge.” Mobile chips, including Ryzen 3000 Mobile “Picasso” up through Ryzen AI 300 “Strix Point,” as well as Threadripper workstation CPUs from Threadripper 3000 “Castle Peak” to Threadripper 7000 “Storm Peak,” are also affected. Older AMD CPU generations have already seen fixes for this vulnerability, but the AGESA 1.2.0.3e firmware is specifically aimed at AM5-based platforms.

    It’s vital to point out that these BIOS updates are permanent on some motherboards, particularly those from Asus, meaning users cannot revert to earlier firmware versions after installation.

    Additional Update Benefits

    In addition to addressing the security flaw, the update also prepares motherboards for the upcoming Ryzen processors, expected to be part of the Ryzen 9000F series. Moreover, this update enhances compatibility and performance for high-capacity memory configurations, especially those utilizing 4×64 GB DRAM modules with speeds ranging from 6000 to 6400 MT/s.

    Radeon RX 9070 XT: Samsung Memory Slower than SK Hynix

    Key Takeaways

    1. AMD is transitioning to Samsung memory modules for its Radeon RX 9070 XT graphics cards, replacing the original SK Hynix supplier.
    2. Performance tests indicate that Samsung-equipped models are 1% to 2% slower than those with SK Hynix memory, based on synthetic benchmarks.
    3. The actual gaming experience may not be significantly affected by the slight performance difference observed in benchmarks.
    4. AMD confirmed that the performance drop is linked to the use of Samsung memory, which also offers improvements in thermal management.
    5. Radeon RX 9070 XT GPUs with Samsung memory showed higher power consumption and clock speeds, but performance differences are minor and likely unnoticed in real-world gaming.

    Evidence has emerged that AMD is shifting to memory modules developed by Samsung for its Radeon RX 9070 XT graphics cards. Reports indicate that these new models perform a bit lower than those with SK Hynix memory, which was the original supplier. However, the actual gaming experience might not be impacted, since the comparison relies on synthetic benchmarks.

    Performance Insights

    A tech reviewer from China observed a drop in performance in certain Radeon RX 9070 XT GPUs. After conducting tests, the reviewer discovered that GPUs equipped with Samsung’s GDDR6 memory modules were performing about 1% to 2% slower than their counterparts using SK Hynix modules. In a video, the reviewer compared more than 20 different models of the Radeon RX 9070 XT and highlighted this performance gap.

    Confirmation from AMD

    Additionally, the reviewer had a conversation with a member of the AMD team in China, who allegedly confirmed that the slower performance was indeed related to the use of Samsung modules. When the initial evidence of the switch to Samsung memory appeared, it was thought that this change aimed to enhance thermal performance. The report suggests that using Samsung’s memory did provide noticeable improvements in thermal management.

    Power Consumption and Clock Speeds

    Interestingly, the Radeon RX 9070 XT GPUs with Samsung memory tested recently showed higher power usage and clock speeds, yet still exhibited slightly inferior performance.

  • AMD Zen 7 Desktop CPU Core Count Leaks: Up to 2x Increase Over Zen 5

    AMD Zen 7 Desktop CPU Core Count Leaks: Up to 2x Increase Over Zen 5

    Key Takeaways

    1. AMD is developing five different versions of the Zen 7 CPU architecture, focusing on performance and efficiency.
    2. The Zen 7 “Classic” desktop CPUs are expected to have up to 32 cores and 64 threads with Hyperthreading.
    3. The Zen 7 consumer CPUs will feature significant IPC and clock speed improvements, along with increased core counts compared to Zen 6.
    4. A top-tier Zen 7 Ryzen 9 CPU may have 50% more cores than the flagship Zen 6 chip, making it an attractive upgrade for Ryzen 9000 owners.
    5. Zen 7 is still over two years away, and current specifications may change before release.

    Around May, it was reported that AMD might be working on as many as five different versions of the Zen 7 CPU architecture. Each of these versions has unique design objectives, with some concentrating on pure performance and others on efficiency. The Zen 7 “Classic” aimed for desktop AM6 platform is said to be focusing on improvements in IPC and clock speeds.

    Core Count Increase

    New information from Moore’s Law Is Dead suggests that, in addition to the IPC and frequency enhancements, the Zen 7 consumer CPUs will also see a significant increase in core count compared to Zen 6. According to MLID, this information comes from one of his top sources at AMD.

    Specifications and Features

    The Zen 7 “Classic” desktop CPUs are expected to feature up to 32 cores, thanks to dual 16-core CCDs. With Hyperthreading enabled, this means there could be an impressive 64 threads available. However, the previously leaked “3D Core” variant seems not to be available for the consumer versions of Zen 7 CPUs.

    As per MLID, the Zen 7 chips designed for the AM6 platform will include “lots of V-Cache,” since the 3D Core design is not likely to be included in the consumer CPUs. Nevertheless, both the Zen 7 consumer CPUs and the 3D Core variant are believed to have IPC that is “comparable,” with the “Classic” cores featuring higher voltages and clock speeds.

    Potential Upgrade Path

    A top-tier Zen 7 desktop Ryzen 9 CPU might boast 50% more cores than the flagship Zen 6 chip, which is rumored to increase its core count to 24, effectively doubling the cores of the Ryzen 9 9950X. When you add in the IPC improvements and potentially much larger 3D V-Cache, those who currently own a Ryzen 9000 CPU could find themselves with a compelling reason to upgrade in 2028.

    MLID also cautions in the video that Zen 7 is still over two years away. Thus, any technical specifications leaked at this stage might be subject to change.

    AMD to Launch Stronger RDNA 4 Variants to Compete with RTX 5080

    Key Takeaways

    1. AMD is reportedly developing a premium RX 9080 XT model and plans to update its RDNA 4 graphics card lineup in 2025.
    2. New Radeon GPUs targeted at professionals may feature up to 48 GB of VRAM and are expected to launch soon.
    3. Stronger variants of RDNA 4 graphics cards are anticipated later this year, potentially including the RX 9080 XT.
    4. AMD aims to enhance its presence in the high-end GPU market, especially as Nvidia shifts focus to AI and reduces RTX 50 stock.
    5. AMD’s improved GPU drivers and technologies like FSR 4 may give it an advantage over Nvidia’s offerings in the upcoming high-end GPU segment.

    We shared recently that AMD appears to be working on a premium RX 9080 XT model. Moore’s Law Is Dead has also mentioned a possible launch schedule for revamped high-end RDNA 4 graphics cards, based on info from various AIB and industry insiders.

    Possible Refresh Timeline

    According to MLID, an AIB source indicated that AMD may be updating its lineup sometime in 2025. There’s also speculation that Team Red could introduce new Radeon GPUs aimed at professionals, featuring up to 48 GB of VRAM.

    Stronger Variants Coming

    Another AIB contact reported from “AMD representatives” that there will be “strong variants” of RDNA 4 launched later this year. Although the specifics of these “stronger” RDNA 4 models remain unclear, it is reasonable to think that the RX 9080 XT could be among them.

    So what are the implications of all this?

    AMD’s Market Positioning

    To begin with, AMD might be preparing to fill the gap in the high-end/flagship segment of the RDNA 4 GPU range. With an RTX 5080 Super challenger on the horizon, AMD could significantly enhance its presence in the gaming sector, especially since Nvidia is reportedly reducing its RTX 50 gaming stock to shift focus to the AI market. Thus, while gamers might struggle to find high-end RTX 50 models, the new RX 9080 XT could serve as a solid alternative.

    When the announcement surfaced in 2024 that AMD wouldn’t introduce high-end flagship GPUs to rival the RTX 5080/5090, fans were left speculating about the reasons behind this. Some believed AMD was unable to get the rumored Multi-Chip Module (MCM) RDNA 4 flagship functioning. Others thought it didn’t make financial sense to enter a market where Nvidia had reigned supreme for several generations.

    Nonetheless, there was an alternative perspective: AMD may have believed that the software ecosystem wasn’t fully developed enough to unleash the full capabilities of the high-end RDNA 4 GPUs.

    Considering this mix of reasons, it appears to be an opportune moment for AMD to roll out a high-end/flagship RX 9000 GPU. AMD currently has robust GPU drivers for RDNA 4, which arguably outperform Nvidia’s efforts with the RTX 50 series, along with impressive FSR 4 technology and promising developments like FSR Redstone on the horizon.

    4. In performance comparisons, the RX 9060 XT nearly matches the RX 7700 XT, achieving 36 FPS in Black Myth: Wukong’s Cinematic mode while overclocked.
    5. A Geekbench listing suggests a 25% to 30% performance improvement over the RX 7600 XT, though 3D Mark Time Spy is seen as a more accurate benchmark.

    AMD is gearing up to unveil the Radeon RX 9060 XT on June 5, which will follow the Radeon RX 7600 XT. A Geekbench listing found last week (between May 26 and June 1) indicated a notable increase in performance compared to the previous model. However, a recent leak suggests it might have even greater performance capabilities. A Reddit user posted benchmark results from Time Spy GPU as well as gaming tests for the RX 9060 XT that featured a slight overclocking of the clock speeds.

    Impressive Benchmark Scores

    Screenshots shared by a Reddit user, who claims to have gotten early access to the unreleased RX 9060 XT, reveal that the GPU achieved a score of 17,069 with an overall score of 14,210. The tests were done using an AMD Ryzen 5 5600 CPU at 1080p. Importantly, it had a mild overclock with a 200 MHz boost to the clock speed and a 40mV undervolt. At these settings, the GPU reached a clock speed of 3.47 GHz while consuming 199W of power.

    Memory Limitations

    The user also pointed out that they could not increase the memory clock speeds past 2,538 MHz, labeling it “un-overclockable.” The benchmark run or system would crash when they tried to go beyond that point.

    Performance Comparison

    In addition, a commenter sought benchmark results from Black Myth: Wukong’s tool, and the RX 9060 XT provided an average of 36 FPS in Cinematic mode (with overclocking), which was merely 3 FPS behind the RX 7700 XT. This performance places the RX 9060 XT nearly on the same level as the Radeon RX 7700 XT, which has an average Time Spy graphics score of 17,113 according to the 3D Mark database. Even though the Radeon RX 9060 XT, specifically the XFX Swift Pro Gaming variant, was overclocked, it managed to match the performance of a more expensive, higher-tier GPU from the previous generation.

    This benchmark result arrived shortly after the Geekbench listing, which indicated a 25% to 30% improvement in performance over the RX 7600 XT, the RX 9060 XT’s direct predecessor. While Geekbench may not be the most accurate for GPU performance, the 3D Mark Time Spy and Black Myth: Wukong benchmarks are considered far better indicators.

    3. ETH Zurich’s research revealed that existing mitigations could still be bypassed under certain conditions.
    4. Intel’s January 2025 microcode update showed minimal performance overhead in most chips, but Rocket Lake experienced an 8.3% performance decrease.
    5. The vulnerabilities affect all operating systems, but AMD and ARM chips are not impacted by the newly identified flaws.

    The Spectre and Meltdown flaws that impacted X86 processors created major issues for Intel and AMD in 2018, leading to lawsuits against both firms. ARM also faced these vulnerabilities, but all companies ultimately issued in-silicon microcode updates to address the bugs. While these updates resulted in some performance loss, it wasn’t severe. In 2022, more Spectre risks were identified for Intel CPUs, including the Alder Lake series, and for ARM cores, with the degree of performance loss varying based on the specific task. Unfortunately, this was not the end of Spectre troubles for Intel, as a new report from ETH Zurich has uncovered additional vulnerabilities for Intel CPUs from 2018 to 2024, some of which show notable performance drops after applying updated mitigations.

    Testing New Mitigations

    ETH Zurich performed detailed examinations of the previously released mitigations, such as the enhanced Indirect Branch Restricted Speculation (eIBRS) and the Indirect Branch Prediction Barrier (IBPB). Their findings suggest that, under certain conditions, these mitigations can still be circumvented.

    Intel’s Response

    In January 2025, Intel rolled out a new microcode with better mitigations, enabling ETH Zurich to assess its impact on newer CPU models. The results indicated that most chips experienced minimal effects, with Alder Lake processors showing only a 2.7% performance overhead, Raptor Lake and Raptor Lake-R having less than 2%, and Coffee Lake-R at 1.6%.

  • AMD Zen 6 Leak: 50% Boost in 3D V-Cache and Core Count

    AMD Zen 6 Leak: 50% Boost in 3D V-Cache and Core Count

    Key Takeaways

    1. AMD plans to increase the CPU core count per CCD to 12 for Zen 6 CPUs, a 50% increase from the 8-core CCDs in Zen 5.
    2. Zen 6 CPUs will feature larger L3 cache sizes, with around 48 MB per CCD for client models and up to 128 MB for server models.
    3. The potential total core count for the flagship Zen 6 chip could reach 24 cores and 48 threads.
    4. Future Ryzen 7 X3D CPUs might offer 12 cores and a total of 144 MB of L3 cache, significantly enhancing gaming performance.
    5. Current information is speculative, and final specifications for Zen 6 CPUs are yet to be confirmed.

    Thanks to a lot of reports that have come out recently, we now have a clearer picture of what AMD is planning with their Zen 6 CPU architecture. The main areas AMD is looking at include increasing the CPU core count, enlarging the L3 cache, and raising clock speeds, which should provide a significant performance boost compared to Zen 5.

    Core Count and Cache Size Updates

    Regarding the increase in CPU core counts and L3 cache sizes, there’s now more evidence about AMD’s intentions. HXL shared information on X, indicating that AMD plans to raise the core count per CCD to 12 for the Zen 6 CPUs. This marks a 50% increase compared to the current Zen 5 Ryzen 9000 CPUs, which utilize 8-core CCDs. Therefore, the flagship Ryzen 9 9950X uses two 8-core CCDs. If this trend continues, the Zen 6 flagship chip could potentially feature as many as 24 total cores and an impressive 48 threads.

    Plans for Epyc Server CPUs

    Moreover, AMD might also be working on 32-core CCDs for their Epyc server CPUs. To fit 32 cores on a single CCD, the cores will likely need to be notably smaller than those found in the client Zen 6 CPUs. Thus, it’s expected that there will be 32 Zen 6c cores per CCD rather than the standard Zen 6 cores.

    As previously mentioned, Zen 6 CPUs will also feature more L3 cache compared to their Zen 5 predecessors. HXL reports that the client “Olympic Ridge” Zen 6 SKUs will have around 48 MB of L3 cache per CCD, while server chips could see a massive 128 MB L3 cache per CCD.

    Comparison with Current Models

    For context, the Ryzen 9 9950X provides 32 MB of L3 cache per CCD, resulting in a total of 64 MB. Thus, the increase in L3 cache could mean that the dual-CCD Ryzen 9 Zen 6 flagship could reach 96 MB total. This is quite significant for average users, and a per-CCD L3 cache of 48 MB is also substantial for gamers.

    The Ryzen 7 9800X3D, which is currently the fastest gaming CPU available, has one CCD with 8 cores, 16 threads, and 32 MB of L3 cache. With a single 64 MB 3D V-Cache stack positioned below the CCD, the total L3 cache amounts to 96 MB. If Zen 6 indeed offers 48 MB of L3 cache per CCD, then the successor to the Ryzen 7 9800X3D could potentially have 112 MB of total L3 cache, assuming AMD maintains the same 3D V-Cache amount.

    Potential for a New Gaming Champion

    This is where things become really intriguing. Kepler_L2 responded to HXL’s post, suggesting that AMD might also raise the total 3D V-Cache from 64 to 96 MB. When combined with the 48 MB of L3 cache for a Zen 6 CCD, a future Ryzen 7 X3D CPU could feature 12 cores and a whopping 144 MB of L3 cache.

    In summary, if AMD does launch a Zen 6 X3D chip with 144 MB of cache, 12 cores, and higher clock speeds than the Ryzen 7 9800X3D, Team Red might just hold onto the gaming performance title for another generation. However, this information is still speculative and based on rumors. The exact specifications of the final Zen 6 CPUs remain to be seen.
