A rather comprehensive review of an upcoming Intel Rocket Lake processor has been shared by a Romanian tech site called Lab 501. The processor put through a wide range of benchmarks, productivity, and gaming tests by the outlet is an 11th Gen Intel Core i7-11700K 'Rocket Lake-S'. However, the site manages to squeeze out this early review as it tested an engineering sample of an ES processor that isn't meant for or tuned for final release. In other words this is one of a series of test chips Intel and partners will work with ahead of launch and will likely be at least a little different to a retail sample.

Sometimes ES chips are quite a bit slower than the ones that are generally released and entered into the Intel Ark. In this particular case though, it is thought that the chip under test is running at the same clocks as the retail version. That might be good, but there are a few other things that could hamper this ES chip performance compared to the eventual retail release – most significantly a further expected microcode update from Intel for motherboard BIOSes ahead of release. The source site, Lab 501, admits this, and suggests that its test results could easily vary by +/- 5 per cent and power/thermal performance could change too.

OK, now we have got that out of the way, how does the Core i7-11700K perform? First, as should be expected it edges ahead of the previous gen Core i7-10700F in all the tests. Comparing it to its contemporary foe, the AMD Ryzen 7 5800X, it typically lags in the benchmarks, utility, and productivity app tests – but it is extremely close and sometimes a little better in gaming tests.

I've downloaded and added some of the performance charts in this article, but the source has many more if you are interested in checking further – take your translator with you for the between charts copy.

Another thing of note here: the engineering sample appeared to run rather cool. In Prime 95, for example, the i7-11700K maxed out at 71 degrees, compared to 75 for its predecessor, and 89 for the 5800X. (All test systems used the Noctua NH-D15 cooler.) However, during these Prime 95 tests the i7-11700K system ate up 286W compared to the 224W of the 5800X system.

Remember, this is a leaked test of an engineering sample on non-final firmware. HEXUS will have reviews of the final release Rocket Lake-S hardware as soon as it becomes available.

Objectively, it looks like it's just a 10900k because that's pretty much similar, loses in multithreaded productivity and trades blows with the 5800x.

What's interesting is the temp being pushed out versus draw, that looks a little odd but we'll have to see as more benchmarks occur on retail samples.

Basically, it looks like a 10900k with PCIe 4.0, not exactly rip roaring…
Looks to slightly beat the Ryzen 7 5800X in gaming,and power draw isn't that bad considering the process node difference. Hopefully the 6C/12T Core i5 is decent,as that should hopefully push prices down a bit.

Could be an ‘offset’ on the temp sensor so it reads lower than it actually is, iirc AMD originally had weird temps due to an offset needing to be applied on release in monitoring programs.

Could be, HWInfo had some serious issues with Zen 1 and reading the temps, CPU-z as well IIRC
5615 in r20 vs ~5k for a stock 10700k is a nice improvement. 286w under load explains where that performance is coming from, though.

Wonder where the 11900k is going to end up.
