AMD Zen 5 rumours
- Thread starter Grim5
- Start date
Yeah, i got through most of that.
A lot of interesting stuff said, but the freshest in my mind is him talking about all these vulnerabilities in both Intel and AMD, AMD have just had a fairly serious one found against them, which this server guy is not happy about but when pushed on the matter he said something interesting.
Comparing the situations Intel wiped out 43% of performance in one go and right across the range, from Sky Lake to Raptor Lake, or their server equivalents, now while this new one for AMD does that too its the first time that's happened, usually if something effects Zen 2 it does not effect Zen 3 or 4, even if these vulnerabilities were discovered long after those CPU are out, so there is clear track record there of AMD always trying to improve the security of their CPU's, each generation is better future proofed than the last. That doesn't exist with Intel and for AMD its 12% performance lost to vulnerabilities in 4 generations.
But more over he went on to say in a more broader sense that it seems to him that Intel's CPU's are kind of, and i quote "Hodge Podged Together" where as AMD's CPU's are clearly much more holistically designed, he also alluded to Moore's Law being very much on a slowdown that now you just can't always go for the best node and improve your CPU's that way, in his view AMD have frankly taken over because they continuously improve their CPU's by design... Oof..... Ouch.

That seems very low, I get ~30.6-31k (7950X). Your clocks are also ~300Mhz higher, Zen 5 is strange. Could be RAM speed is pushing the SOC power up and taking it from the cores. I am running 4800 stock and also disable the iGPU.
i had some really funky behavior just, whole pc was lagging like mad, set a manual pbo of 230w, chip did not like it one bit, almost 40 seconds to get into windows, heavy micro stutter on the desktop and even in the bios, had to clear my cmos.
just read up how to set manual power modes, back to the bios, set 230w, negative 20 offset and tried r23 again, temps around 88.5c, core effective clocks 5.15ghz, scored 44,481

R23 runs entirely in cache, no fabric bottleneck. The gains you see there are purely ipc.
The thought is x3d with more L3 will keep more gaming workloads in L3 without having to be bottlenecked by transferring datasets across the fabric. Of course this will vary game to game so it won’t be a blanket bump across the board.

Yeah seems though at least for games that are UE5 as example aren't anywhere close to doing that so gaming wont be changing at all unless there some way to resolve that sooner than later. If they ever find the magic sauce to resolve at least we know there will be large gains to be had.
I like the way he correctly labels the RAM speeds, it is Mega Transfers Per Second (MT/s) not Mega Hertz (Mhz)
Yeah, it is...
Yeah, it is...

show me other games then
Clearly i don't need to.
well need to see it across number of games to know
Looks like Star Citizen benefitted as much from tuning the RAM (7% gain) vs. 6% gain from the overclock. The gains in 1% lows were even better! It is a memory intensive game?Star Citizen. Stock and tuned... it gains quite a lot from tuning. +13%
I think most game benefit from a memory tune, its not unique in that sense, but it is the most CPU heavy game i know, nothing else comes even close to how CPU intensive this game is, probably something to do with its scale and the fact that everything is physicalised.

I've seen all of my Zen 3's 16 thread's pegged sloid to 100% in it, that was with a 2070 Super, i've not seen that yet with the RX 7800 XT and the bottlenecked performance is very much higher but then Nvidia Drivers use the CPU very differently to how AMD do.
Either way its brutal on the CPU.

Star Citizen is not a game, firstly. Secondly, yes its always being extremely bandwidth intensive in all aspects, including being picky about the type of storage device it's on
Yes they use what they call Hierarchical Object Container Streaming, think PS5, Ratchet and Clank, long before that existed and on a much much more massive scale.
