B840 has even worse PCIe support than A620, huh. All intel B760 motherboards I see feature 4.0(or 5.0) x16 GPU slot though, so why did AMD jump back to 3.0 lol

edit: I figured it out, they want to choke out the 1x4 GPU connection on 8500G even more, it's a genious plan. Because connecting a low-end processor to low-end motherboard must be punished

I guess my paltry scores at very low power vs Zen 4 and Zen 5 have a lot to do with my 12nm IOD vs the 6nm. I didnt bother with going JDEC speeds, I dont think the power addition would have done much.

Zen 3 has the same problem- go above JEDEC and IOD gobbles power. You'd probably notice a pretty good uplift.

Really? We had 3 Gens of Chiplet Ryzens now and you still don't know how they work? There is no benefit of that extra Cache. Every Gen the difference between 8 Core and 16 Core in Gaming was negligible

According to Computerbase the 13900K/14900K are 14/16% faster than the 5800X3D at 720p, you think that this advantage increase at 1080p.?.

Or that it will rather decrease to something like 10%.?.

In wich case 12% faster than the 5800X3D would be slightl faster than these Intel chips, btw i added the 13900K in the comparison because it s set at 253W while the 14900K is at unlimited power in their benches.

Was there any mention that Strix-Point has narrower SIMD units vs GraniteRidge? I took a brief look at the slides, but nothing there. Would be grateful if someone could point them out. Also if I remember correctly David Huang did not measure 2 cycle FADD latency...

At Computex they claimed ZEN5 trashes 14900K. If these Numbers are right, 14900K will be slightly faster instead

Techpowerup has the 13900k being 15% faster than the 5800x3d at 1080p.
Either way, doesn't look like Zen 5 will be much, if at all, faster than RPL.

The "FP slide" doesn't even have an asterisk mentioning the <512b SIMDs. AMD marketing...
 
Isn't the rename stage being separate between INT and FP a new thing? Also, NSQ (the non-scheduling queue) was before the FP schedulers, but now it is before the FP rename. It looks like Zen 5 decouples the FP from INT processing even more, stalling INT less when FP is full... Interesting.

There s dedicated slides for the comparison, think what you want.

We already know the score for 9950X, 5ghz all core = 43K~
5.5ghz 47.3K


Guy said that you need decent cooling and PBO to reach 43K.

My 7950X at stock does 5.3 CCD0 and 5.1 CCD1 in CB R23 on a modest air cooler, and is completely thermally limited. You're telling me that the 9950X will be hotter and clock lower despite literally everything indicating the opposite?

OK.
