  7. AMD has already released its first for one of their CPU architectures, specifically :

    youtu.be/JplSooSb30o

    This is quite big, as it means they are replacing its AGESA with an BIOS.

    And it will be the future for newer Zen's too.

  8. AMD has already released its first #openSIL #BIOS for one of their CPU architectures, specifically #Zen4:

    youtu.be/JplSooSb30o

    This is quite big, as it means they are replacing its #ClosedSource AGESA with an #OpenSource BIOS.

    And it will be the future for newer Zen's too.

  12. Hey #Valve, here is an idea:

    The "Steam Dock", a 1080p@60 machine:

    - Valve Freemont SoC (6@12 Zen4, RX 7600 RDNA3)
    - Steam OS
    - 16GB RAM (8 DDR5 + 8 GDDR6)
    - 512GB / 1TB

    * $199, no controller + 512GB
    * $249, with controller + 512GB
    * $299, with controller + 1TB

    It's basically free money. Hell, I'm throwing my wallet right now to the screen as I'm writing this.

    #Videogames #Gaming #Games #SteamDock #Steam #AMD #ValveFreemont #Consoles #Console #SteamConsole #ValveConsole #Zen4 #AMD

  13. If #Valve can push a console for $199, they will own the market.

    For such old hardware (#Zen4 and #RDNA3), I don’t think they’re aiming for premium price but something that runs well and is accesible. Much like the #SteamDeck.

  14. Sizing up #MI300A’s #GPU
    It’s well ahead of #Nvidia’s #H100 PCIe for just about every major category of 32- or 64-bit operations. MI300A can achieve 113.2 TFLOPS of #FP32 throughput, with each FMA counting as two floating point operations. For comparison, H100 PCIe achieved 49.3 TFLOPS in same test.
    #AMD cut down #MI300X’s GPU to create MI300A. 24 #Zen4 cores is a lot of #CPU power, and occupies one quadrant on the MI300 chip. But MI300’s main attraction is still the GPU.

  15. How to make any #AMD Zen #CPU always generate 4 from RDRAND
    "We have demonstrated the ability to craft arbitrary malicious microcode patches on Zen 1 through #Zen4 CPUs," the Google #Security Team said.
    "The #vulnerability is that the CPU uses an insecure hash function in the signature validation for #microcode updates."
    The flaw listed as CVE-2024-56161 with a CVSS score of 7.2 out of 10, was discovered and reported to AMD in September, and a fix was devised by December.

  21. In other words, Intel didn't design their #ArrowLake architecture with #3DVcache in mind, so consumers will have to wait years for something similar.

    What's worse, AMD has 3D V-Cache processors for $200, $300, $400 and $500. Regardless of benchmarks, X3D = gaming and Intel has no direct response.

  22. You know? I'm also targeting previous gen sales.

    It's either a giant leap with #AppleM4, or just almost-same performance with the prior #Zen4 and #MeteorLake laptops. I can trade efficiency if that's the case.

  23. Honestly, I don't see the point of having a third-party #SteamDeck going for more than $600. Makes no freaking sense.

    After that price these compete in the #laptop space, where you can find superior SoC on all sides: #Zen4, #Zen3, #MeteorLake or #LunarLake. These win hands down no contest.

  28. #Zen5 Variants and More, Clock for Clock
    They compare #Zen 5 variants along with a pile of older cores with clock speed taken out of the equation as much as possible. That means capping clock speeds on all CPUs to the lowest clocking chip. In this case, that’s the #3GHz Athlon II X2 651.
    Desktop Zen 5 takes a healthy 20.8% lead over #Zen4 in the most comparable configuration. #VCache gives Zen 4 96 MB of L3 cache which shrinks Zen 5’s lead to a still significant 16.6%.

  34. #AMD #Zen4 vs. #Intel Core Ultra 7 "#MeteorLake" In 400+ Benchmarks On Linux 6.10
    The #CPU performance for the #Ryzen7 #7840U was around 27% faster than the Core Ultra 7 #155H while the #Ryzen 7 #7840HS was about 35% faster than that Meteor Lake laptop. AMD Zen 4 wins were all the more compelling when looking at power consumption with 7840U consuming 27.1W on average across all benchmarks with a peak of 51W compared to Core Ultra 7 having a 29.6W average and peak of 65 W.

    The 5th Gen AMD EPYC processors are built atop #Zen5 and will come in designs up to 192 cores / 384 threads per socket! Presumably the 192 core processors will be leveraging #Zen5C cores.
    The top-end #Ryzen9000 has 16 cores and 32 threads and runs at 5.67 GHz turboed up, and the Zen 5 cores are averaging 16% more instructions per core than #Zen4.
