News Intel Core i9-13900K Benchmarked in Chinese Video, Delivers 10-35% Perf Increase

[Admin]

The new Raptor Lake chip is on average 10% faster in single threaded workloads, and 35% faster in multi-threaded workloads, than its Alder Lake ancestor.

Hesitant to be impressed with these numbers until I see some power draw figures.

If it took 400 watts of power to achieve those numbers then IMO its a huge failure.

It won't. Raptorlake power specs were leaked a while ago and the PL2 is slightly higher at 250W vs 240W for Alderlake.

Uh? What are they calling "PL4"? Given the power numbers in parenthesis from their table, is it the "unlimited power" mode?

And 5.5Ghz with 1.34v... This may actually consume more power on average while increasing the ceiling just a bit for all-core (well, so the numbers on paper agree/show). The gains don't seem bad, but there's a lot more to find out for sure.

So far, cautiously optimistic.

PL4 is the maximum that is allowed and the CPU will not go above that

So it's the CPU power ceiling configured (configurable?) by the AIBs and OEMs for the platform. So I'll guess true OC boards have unlimited PL4? Otherwise OC records wouldn't exist XD

Anyway, thanks Terry!

It's unclear if it can be programmed, the fact that they say it's disabled by default might suggest that it is.

The extreme cooling in overclocking actually drops the power draw to really low levels, the less movement there is from the electrons the easier it is to move them around and make them stay where they have to.
12900k unlimited power 4.9Ghz all core running cinebench at 160W...all you need is a little liquid nitrogen ¯\(ツ)/¯ .

Damn im cheap... 5Ghz base clock is what I am waiting for, 2 more gens or 3 you figure? 4 on the outside or am I dreaming?

Considering the power specs are pretty muxh the same as Alder Lake with possibly more controls... very unlikely. Especially in everyday work and gaming workloads.

At least, the document/image you posted makes me believe that is the case.

Well, the answer is a tad more complicated, but not wrong on principle: the closer you're at "superconductor" level, the less resistance, less energy needed to move stuff around. So yeah. That being said, you still do need a lot of power to reach world records. I recall der8auer or Kingpin saying they do work towards 900W for GPUs, also using liquid nitrogen for cooling, so I'd imagine CPUs are not that different. More than likely not 900W, but 300W or even 400W doesn't seem too unrealistic for all-core OC records.

Also! This is relevant from another conversation in another thread/news. Quite interesting findings that agree with the common understanding of most of us here:

It is always nice to see these things against hard data, but at least this time the common intuition/anecdotal evidence aligns perfectly. We're stll perfectly ok with 8-core CPUs for 99% of people and about 100% of gamers. The 6 core CPUs are just a tad less performant (~5% range when loaded), but the different is to minuscule that it's mostly irrelevant. For multiple apps and such, what matters more (at or above 6 cores) is available RAM to just have all that software open. So, 6 core CPUs are perfectly viable and 8 cores (and above) are just for when you know you need the extra CPUs or at least know you will put them to use at some point.

So it looks like performance in games and standard productivity workloads (burst work and wait) will only see a modest performance increase over last gen. Only when all cores get 'lit up' will the performance difference really show.
As more programs and games become natively aware of the E-cores, overall performance will increase but that is yet to be realized.

The gain in gaming probably won't be quite as big as the 5800x to 5800x3d, but certainly larger than the clock speed bump. Combine the 2 and it might be close. Modest is a relative term.

This is much better than what I was expecting from Raptor Lake. I was thinking 0-5% single core performance on the outside, but these benchmarks show 10%+ and mostly around 12-14%. Multi-core of course is much higher like +30%. I wouldn't call it revolutionary, but this is a pretty serious bump in performance for just one year after Alder Lake, assuming they can hit their release targets this year.
