Can you imagine what will Zen 4-3d do to Intel? damn, Zen 4 is a beast, and userbenchmark is Intel enemy now :).
Can you imagine what it will do to your wallet

I did the benchmark on a 12700k @ stock
Base clock 3.6 GHz, turbo 4.65 GHz (avg)

Memory 84.9
1-Core 194
2-Core 368

117% 216 Pts
4-Core 752
8-Core 1,498

138% 1,125 Pts
64-Core 2,437

164% 2,437 Pts

for a base clock of 4.4 and turbo avg of 4.95 that 7600x seems pretty weak imo

Impressive result, but the 12900k does not get 200 pts. Just tested it, scored 237 at stock 270 overclocked
That's interesting. I can believe that Zen 4 CPUs have slightly higher SC performance than a 12700K or 12900K.

But the 12th gen still retains the multithreaded crown, due to the extra 4-8 E-cores (even more with 13th gen).

The 6/8 Zen 4 CPUs look like very good value if the rumoured prices are correct, but they seem to good to be true, relative to Intel pricing.

EDIT - forgot about 20% VAT on top. Suppose that sounds about right. Hopefully there will be a cheaper 8 core '7700X' on launch. The spec looks a bit wrong, I think the 7700X will probably handle 5.1 or 5.2ghz all core, hopefully even with AVX instructions.

Not sure I believe that the 12 core CPU will cost 2x the amount of the cheaper 8 core variant...

I wouldn't be that surprised if the 16 core part ends up consuming upto 230w :eek:, as suggested

Will have to wait and see on pricing but I can't see AMD pricing as high as they did with zen 3 as consumers will have additional board and ram costs added in this time around.

More here, this is the 7600X running at 4.4Ghz.
Its compared with the 5950X, i don't think the thread count matters much if anything, assuming not, it is a 32 thread CPU vs a 12 thread CPU, we should just look at it in terms of clock speeds.

In games the 5800X runs at 4.85Ghz
Not sure about the 5950X but it is higher, about 5Ghz, lets go with that.

5.0 / 4.4 = 13.6%
Average FPS: 9.5% higher than the 5950X

13.6 + 9.5 = 23.1 That's 23% higher IPC (in this case)

If the final 7600X runs at 5.2Ghz that's another 18% on top of the 9.5%, a total of +27%

I've had this link for a week, didn't really want to post it unless something similar popped up from someone else, but #### it, make of it what you will.

IMO its too far fetched!/ It would make the 7600X faster than the Ryzen 5800X3D.

I had no idea, same power envelope as me and you wouldn't be putting a higher load on the CPU than me, so while of course i take what you guy say as fact, i don't get it. :)

This is +50Mhz and some curve tweaking, out of the box its not much worse than this.

CPU clock 3'rd line down

Do we even know if the userbenchmark entry for they 7600X (Zen 4) is even real? The people running the website seem reluctant/sceptical about the result.

The AM5 socket is apparently now officially supported by the AK620 cooler I bought a few weeks ago:

Support for "AM5/AM4". Nicccce.

I wonder if that means it will work with the kit I got in the box, or if I'll need an extra mounting bracket?

Out of curiosity, how much are people here willing to spend on a 7700X, or slightly better 7800X?

I personally would be reluctant to spend much more than £300.

It will work with the AM4 brackets as AM5 was designed to be backwards compatible with AM4 coolers

If you ever feel the need, the ak620 supports a 30mm thick fan on the middle. Which means you can swap the stock fans with 2xT30 120s. That would probably make it the best performing air cooler on the planet ;)
