At Computex they claimed ZEN5 trashes 14900K. If these Numbers are right, 14900K will be slightly faster instead
I am sorry but the 9700x only consumes up to 88 watts. If the 14900k needs >150 watts to beat the 9700x I don’t consider that a win.

Efficiency is king. Also don’t trust whatever Intel or AMD say in their marketing it’s all cherry picked.

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...

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.
