    Discussion PES | Assessing Power and Performance Efficiency of x86 CPU architectures

    3900X + PBO fmax enhancer (ASUS' official EDC bug for Zen2), stock PPT TDC EDC (142w 95A 140A), 1900MHz fclk / 1900MHz uclk / 3800MHz mclk so the I/O die eats some more into the total power budget than usual. Really nice to see efficiency going up with newer generations. Zen4 in particular is...

    Discussion Speculation: Zen 4 (EPYC 4 "Genoa", Ryzen 7000, etc.)

    Even if there is no low power/non X part available, you can make one yourself that's a good enough replacement even if the silicon hasn't been binned with low power first in mind. Lower PPT/TDC/EDC to the 65w bracket values (88W/60A/90A)... or enable eco mode. Same thing. Undervolt while you're...

    Discussion Speculation: Zen 4 (EPYC 4 "Genoa", Ryzen 7000, etc.)

    Sisoft did the same with their Zen3 results before NDA was up. Their synthetic suite predicted quite well how things did in real life not much later. You can find all these posts in the Zen3 speculation thread. If people light up at the results (me included) it's because there's precedent that...

    Discussion Speculation: Zen 4 (EPYC 4 "Genoa", Ryzen 7000, etc.)

    I know. Amazing stuff! I think there won't be any shortage of x86 innovation for the foreseeable future with this AMD. I fear TSMC hitting a roadblock on future nodes like Intel did with 10nm stalling progress more than anything. Anyway. I need leaks now. Come on reviewers, throw us a bone!

    Discussion Speculation: Zen 4 (EPYC 4 "Genoa", Ryzen 7000, etc.)

    Lovely results, as expected. Even considering the increased power usage to make it happen, it's impressive. Golden Cove seems so wasteful in comparison, much like Ice lake / Tiger Lake vs Zen3. Much larger structures overall but lackluster results. There's this interview with Mike Clark that...

    Discussion Speculation: Zen 4 (EPYC 4 "Genoa", Ryzen 7000, etc.)

    That statement was made in context of having to deal with AM4's original restrictions. It started out with single chips (Bristol Ridge, Summit Ridge, Pinnacle Ridge) then transitioned to chiplets. AM5 has been designed from the ground up with chiplets in mind. We've already seen Genoa delidded...

    RapydMark CPU benchmark

    Now that you mentioned it, the results in my other post were done with sz's Ryzen balanced v4 power plan. Zen2 is very sensitive to power plans, that one nets snappy performance with lower temperatures on day to day usage. Some workloads do suffer a performance hit. This is how it behaves with...

    RapydMark CPU benchmark

    Highly tuned 3900X (PBO Fmax enhancer) + memory (4x16GB DDR4-3800 16-19-19-38-57 1T+GDM, as tight secondaries and tertiaries as Rev. E will do) Zen3 is quite the improvement here.

    ASUS A320 boards boot Vermeer with the new BIOSes. They're even listed in the CPU compatibility list. Asrock's A320 boards do, too. Link to one Biostar started distributing A320 BIOSes based on the same AGESA v2 1.2.0.3c release. Vermeer support, too. Vermeer on A320 is not a gigabyte only...

    Info Asus, Gigabyte and Asrock adding Vermeer and Renoir support to A320 boards. (Update: 1.2.0.7 adds Cezanne support to 300 series)

    Then why allow Vermeer for A320 if Renoir was the point all along? Why anger the userbase that way? Why give possible first gen AM5 owners every reason to stay away from the platform if they care about longevity and support in the future? This is another "Poor Volta" level move from AMD's...

    Info Asus, Gigabyte and Asrock adding Vermeer and Renoir support to A320 boards. (Update: 1.2.0.7 adds Cezanne support to 300 series)

    No, it doesn't work. A320 gets Vermeer, but B350/X370 get Renoir. What the f*** AMD. I guess they just don't want to sell more CPUs and are happy letting Intel take the cake with B660 and cheap Alder Lake in a litle while.

    Cezanne doesn't boot on these new B350/X370 BIOSes, just like in A320's case. Got everything needed in the BIOS, but the lock is still there. We still don't know anything about Vermeer. Damn it. Someone has to have one of Gigabyte's boards and a 5000 series CPU to try... I don't like the...

    Zen 2 APUs/"Renoir" discussion thread

    That SoC should have never left the PS5, not in this state. Latency seems in line with what others reported, it's GDDR6 after all, bandwidth over latency. Can hwinfo read the SVI2 TFN telemetry to read how much power it's consuming?

    Question 3950x Prime95 Clock speed

    Now that's more in line with what's expected. These CPUs behave more like current GPUs (think of nV's GPU boost 3.0/4.0 based GPUs, AMD's Vega and Navi cards), in which clockspeed is highly variable and highest when the workload is light, pushing enough voltage to sustain that clockspeed while...

    Question 3950x Prime95 Clock speed

    Is 1.325v your FIT voltage? If not, you're gonna degrade that poor 3950x. You should be aiming for ~1.2 - 1.25v if you want a fixed manual all core OC on the dual CCD parts (3900x, 3950x). Having said that, you're not going to do better than the boost algorithm on Zen2/3000 series CPUs. Disable...

    Going by current 5700XT performance as seen in Techspot's 6800 review, that card is ~10% slower than the 2080S on average at 1080p, and that gap increases to ~14% on average at 1440p.

    2080S? With all the perf/clk improvements RDNA2 has (+21%), plus that ridiculous frequency (~2850MHz gfx clk) the 6700XT should probably be at ~2080Ti/3070 level at 1080p, but probably not quite make it at 1440p. Still closer to them than the 2080S I guess. It all comes down to how much IC AMD...

    It is. 7403 IIRC is the last BIOS for the C6H where PCIe 4.0 works. IIRC for most people it worked fine, but some people with 5700XTs were having issues. In the later AGESAs that limit things to PCIe 3.0, the problem disappeared. I agree, that was a risky one to leave enabled without...

    I guess there's some optimization to be done in this case, as all current games have their RT implemented and optimized against nV's way of doing things. A patch or two later could improve that. Rasterization performance is awesome.
