Today we can finally show y'all how Intel'due south new octa-core 9th-gen processors perform. At that place's a lot to go over, then we won't waste product much time going over the specs considering the CPUs take been up for pre-order now for 10 days now and aught from the spec sheet is a mystery.

On mitt for testing we have the Core i9-9900K -- actually we concluded up with a few of these, with more tests and comparisons in the works for later on -- and we besides have the i7-9700K which is basically the aforementioned CPU, merely crucially, with Hyper-threading disabled.

The Core i9-9900K is an 8-core processor with Hyper-threading enabled for 16 logical threads. It operates at a base of operations frequency of 3.6 GHz simply will boost equally loftier as iv.7 GHz on all cores with a maximum single core frequency of v GHz. The L3 cache has been increased from the 8700K's 12MB upwards to xvi MB and quite shockingly despite packing 2 more cores and 4MB more cache, the TDP rating remains at 95 watts which was already a suspiciously low rating for the 8700K. Nosotros'll explore the impact of this in a fleck.

The Cadre i7-9700K packs the same eight cores just can only process 8 simultaneous threads. Information technology comes clocked at the same 3.6 GHz base frequency while the all-core and single-cadre clock speeds decreased by a marginal 100 MHz. The L3 cache chapters is dropped downward to 12 MB, too.

For testing nosotros're using the MSI Z390 Godlike, but also used the Asrock Z390 Taichi Ultimate to ostend the results. Both boards were tested using DDR4-3200 CL14 retentiveness and this same retentivity was used on all platforms without any manually-tuned timings. The graphics card of choice is Gigabyte'due south RTX 2080 Ti Gaming OC. Nosotros have loads of results to go over so let'southward get started!

Benchmarks

Kickoff upwards we have the memory bandwidth results and unsurprisingly the new Java Lake refresh CPUs are on par with previous models such every bit the Cadre i7-8700K. So everything is equally expected here, let's check out some Cinebench results.

As expected the 9900K and 9700K provide the highest out of the box single thread scores nosotros've seen to date, easily breaking the 200 pts barrier thanks to a v and four.nine GHz clock speed when using just a single cadre.

With all cores active the 9900K breaks the 2000 pt bulwark making it xiv% faster than the Ryzen vii 2700X. Meanwhile the 9700K was managed a score of but over 1500 pts that placed it just behind the sometime 1800X and only ahead of the 8700K. That too meant information technology was 26% slower than the 9900K.

Given what we saw in Cinebench it's no surprise that the 9900K outclassed the 2700X in Blender, reducing the workload completion time by rather large 23%. The 8-core Ryzen CPU was a fraction faster than the 9700K though.

Moving on to Corona and here we find a like story, the 9900K reduced the return time by 20% from the 2700X, taking just 96 seconds. Though if your mostly rendering and then the Threadripper 2950X makes more sense and I'll talk more about that a piffling afterwards on.

The last rendering awarding we tested with is Five-Ray and hither the 9900K reduced the return fourth dimension by eighteen%, taking simply 62 seconds opposed to 76 seconds for the 2700X. The 9700K was a lot less impressive, taking a few seconds longer than the 8700K, making it slower than both the 1800X and 2700X.

The PCMark x synthetic gaming criterion relies heavily on both clock speed and core count, that said it's interesting to see the 9900K only matching the 2700X here while the 9700K was able to edge ahead of the older 1800X.
