Will you pre-order or buy a Rocket Lake CPU?

Fair enough. Another reason some people might choose Rocket Lake, is that the early reviews showed it in a bad light. I suppose it's possible we *might* see performance improvements in the final reviews. The thing is though, these were full retail CPUs running at the intended clocks, not engineering samples...

Personally, the only one I might still consider is the octa core 11700F, which is ~£100 cheaper than the 5800x. Ofc, a cheaper 5800 (oem) / '5700x' would blow both these options out the water, but it ain't happening...

I'd go for a Ryzen 5800x at £350, but the RRP is $449 at the moment, $150 higher than the 5600x.

I'd guess they are having trouble producing them, as they never seem to be available to buy direct from AMD.

Well, the 5800X is expensive in the US too. I think it's mostly because it's the best CPU for gaming (more cores barely makes any difference atm) and AMD knows they will sell them all with relative ease.

Agree, Intel gets nil poi for pricing, just look at Rocket Lake, much more expensive for max 5% perf improvement, and perf. regression in some cases.

Add to this, a memory controller that is likely worse than Skylake based CPUs like Comet Lake.

According to this, the Rocket Lake memory controller is limited to 3733mhz, at 1:1 (Gear 1), even on an expensive 'Z' series motherboard. Link here:

TLDR

There may be problems caused by the microcode that affect the 11700k's 'uncore' / cache frequency, if so, the results of the 11700k Anandtech article may have been impacted.

Probably needs to be tested again with a fixed cache frequency on all tested CPUs, may need improved microcode.

Some games can benefit significantly from higher 'uncore' /CPU cache frequency, example here:

It would be interesting to see how well it performs with the 'Uncore' / Cache frequency set to the same frequency as the CPU core frequency.

This guy has the cache frequency (North bridge clock) running at 3.8Ghz, with the clock frequency at 4.9Ghz.

I'm not quite sure what to think, as the RAM latency in the above test is about the same as my i7 4770K, at 50.3ns...

My upgrade from 4770F to 10700KF (preowned) was pretty damn cheap, total cost ~£210, because I sold my old parts for £200.

I think the upgrade from low spec DDR3 to decent DDR4 is worth it... and a doubling of CPU core count in my case.

My dad had some spare thermal paste, I used the same super old Hyper 212 Evo cooler, plus my brother's old mid tower case.

The cooler keeps the CPU (~4.7ghz all cores) at 80 degrees or under in stress testing (tested with hyperthreading off). Probably could run with HT on with a new cooler.

I'm glad I didn't spend more to get a 10900F, pretty sure the cooler couldn't handle it.

The build went pretty smoothly, except for fitting the hyper 212, it's always a pain to install because you need to get the holes correctly aligned on both sides of the mobo, before tightening the screws.

I'm testing to see if the DDR4000mhz RAM will run at 4133mhz + XMP profile (reviewer managed this), no luck on 1.45v, so testing with 1.490v (HWinfo reports as 1.480v) - Is that a safe voltage for DDR4?

Depends on the actual memory chips. It's safe to daily 1.5V with Samsung B-Die and Micron Rev. E for sure, but on some other ICs it's not. Corsair use every IC under the sun in their products, but they have a version number on the sticks (and probably the packaging) that will tell you what chips are inside. Just do a search for it and you'll find lists of which version numbers correspond to which ICs.

My BIOS says the manufacturer of the modules is Samsung (For Patriot Extreme Performance Viper Steel).
