Intel Core i9-10900 10-core CPU Pictured

Intel's desktop Comet Lake-S lineup is close to being released and we are getting more leaks about the CPU models contained inside it. Perhaps one of the most interesting points for Comet Lake-S series is that it brings a boost in frequency and boost in core count, with the highest-end Core i9 processors going up to 10 cores. Thanks to Xfastest, a Hong Kong-based media outlet, we have first pictures of what appears to be an engineering sample of the upcoming Core i9-10900 processor.

Being a non-K version, this CPU is not capable of overclocking and has a fixed TDP rating of 65 Watts. Compared to 125 W of the K models like the upcoming Core i9-10900K, this CPU will output almost half the heat, thus requiring a less capable cooling solution. The CPU is installed in LGA1200 socket, which is a new home for Comet Lake-S CPUs and provides backward compatibility for coolers supporting LGA1151. In the sample processor pictured below, we can see a marking on the CPU that implies 2.5 GHz base clock. Previously rumors were suggesting that this CPU version has 2.8 GHz base clock, however, it can be an early engineering sample given that no official imprints are found on the CPU heat spreader.

JackCarverNice conclusion :D
In the most games Intel is clearly dominating AMD, read some Benchmarks at this stuff, and I don't think that will switch in the future, but let's see.



And here comes AMD:

+4.7% with 4 less cores and 8 less threads no M2 4.0 makes 9900k a terrible value for my money

MikeZTMQuick question: what's your ram latency in AIDA64 ram test? (you can do this in trail version)

Do you know that currently most games are RAM latency bounded? Intel's gaming advantage is mostly coming from better IMC that can run 4000+ rams ad have less than 40ns latency.

9900KS is not faster than 8086k in those games as less core = less latency for Intel.
See attached. Yes I've explained that to many AMD fanbois. Games are very latency dependent as well as raw clock speed (and IPC obviously). In my real world experience; I've seen 9900k always beat 8700k/8086k due to same IPC, clocking higher on average, more cores to help balance background programs. The very slight latency advantage 8086k has is real, but small. Ryzen has a much higher latency wall to fix and is a much better argument.

AMD's IF latency is much higher yes, but the latency inside a single core and a single CCX is actually slightly lower than Intel's ring bus. This being a 2700X, you can also expect that the 3000 series further improved on this.

Interesting, thanks for sharing that. Looks like the cross-CCX still needs to be vastly improved though.

Cross-CCX latency has a part to play but memory latency is more of a suspect for gaming performance. This is considerably higher for Ryzen 3000 series than Intel's for now and actually a bit higher than Ryzen 2000 series.

Techspot has some directly comparable latency graphs:

3600 is no where pushing the IMC of 9900k/8086k. Try 4200 with tight timing and you will see the difference.
Sub 40ns latency is really hard on 9900k but much easier on a 8086k.
