I know that SiSoftware benchmark is not scaling linearly in 2p but these numbers are really not impressive for sapphire rapids(when compared to previous gen Xeon)

I wasn't aware that Intel also has been a member of the secret association that has sworn to make everything on Earth, even the tradition of April's fool excruciatingly cringe.

But then I've been informed about their initiative called 'Pixel Pat', so now I know.

First Review of the 12900KS. Is it enough to rain on the 5800X3D release?

I doubt it.

From the TPU review:

For the 12900KS, I started with all cores set to the same x49 multiplier for 4.9 GHz all-core and increased the voltage until I got close to the thermal limit of 115°C when running Prime95. Unlike other Alder Lake processors, including the Core i9-12900K, the KS has its out-of-the-box default thermal limit set to 115°C, not 100°C. 115°C is the highest manual setting you can pick in the BIOS for all Alder Lake CPUs. Since this is the default setting, Intel's warranty will cover operating the processor at up to 115°C, which is a good hint for users of other Alder Lake processors based on the same silicon; there's no reason those can't withstand 115°C, too.

In terms of voltage, I settled for 1.35 V and started increasing the multipliers until the system got unstable. Increasing the clocks increased the heat output, so I had to dial down the voltage a little bit—the idea here is to pump as much (or little) voltage into the CPU as the cooling solution can handle as heat. At that voltage, I was able to run at 5.3 GHz almost stable, so I settled for 5.2 GHz all-core for our OC testing. Since 5.2 GHz was rock-stable immediately, there was a little bit of headroom to reduce the voltages further, which brought down power and heat a bit. If you have a high-end custom water-cooler, I'm sure you could easily go to 1.4 V and above to reach 5.4 GHz all-core or more.

This is a significant improvement over the i9-12900K, where I maxed out at 5.0 GHz—seems the new KS is better-binned indeed.

This CPU is perfect for Siberia.

In short, useless and completely unnecessary CPU model.Stretched to the maximum, in an attempt to be better gaming CPU.

- R7 5800X3D hey we offer something different + new/interesting way of CPU L3 Cache packaging

- i9 12900KS, brute force or stretched to the maximum, we have no other options anyway

I agree with this, it's a Pentium 4 EE release

If you want a good bin on a 12900k, there you go. It's like Silicon Lottery but direct from Intel.

The original, Extreme Edition was a repurposed Xeon MP chip, so no I wouldn't say it's been "EE all along". After the first EE the rest has been just souped up consumer chips.

Sad and wasteful the way companies approach to take the halo spot. It's a wee bit better than 12900K. Actually margin of error differences.

I know its an Intel thread, but its not all companies approach. Look at the 5800X3D. It has extra value for the $$$$, not just binned and overclocked from the factory. Intel just has no other way to beat AMD at the moment. The only thing they are king of at the moment, is gaming, and in 18 days that most likely will change.

It IS waste in that a 12900K is enough, and 5950X is enough. Both are there to take the Halo spot, that's all. The actual focus should be on Zen 4 and Raptorlake. 10% faster in gaming? Who cares?

If money were no object, I would buy two. One on the right side of my bed, one on the left. Perfect for keeping me warm on those awfully cold nights. Cheaper solution than two 3090 Ti's.

Here I am stuck in the middle with you."

5800X3D sole purpose of existence is to recapture the Gaming Crown from Intel's Hot/Power Hungry/Inefficient grasp. to be honest if I were AMD I would have not bothered since that lead is within single-digit at High Rez gaming(no one buys a 12900K or 5900X to game at 720P those benchmarks are for academic purposes).

RL is a refresh of AL, I would not expect much gaming performance boost.

Funny you say that, considering RL is rumoured to include a sizeable cache bump, which is supposed to significantly improve gaming performance right? Can't have it both ways. Can't beat AMD with the uber caches? Join em ;)

If the leaks are accurate, Raptor Lake’s L2 cache sizes will increase from 1.25 MB to 2MB for each P core and 2MB to 4MB for each E core cluster. This would mean a total of 32MB of L2 cache for all cores and 36MB L3 cache for all cores. This delivers the grand total number of 68MB.

That could really bite AMD in the ass if true. We always knew AMD would go to 1MB of L2 but now it might have to compete with cores that come with twice that?
