- TPUOverclocking, while easily thanks to the unlocked multiplier, is slightly complicated by the 95 W TDP limit of the 9900K, which will automatically drop clocks when it senses too much power draw. For example when set to 5 GHz all-core, with some extra voltage, as soon as you put a serious multi-core load on the CPU, the clocks will drop instantly to around 4 GHz. To raise this limit, you'll have to adjust the power limit in BIOS or XTU — a first for Intel, but no problem, as long as you are aware of it.
The same power capping mechanism also limits the CPU's boost clocks, even when running completely at stock. Since the processor is specified to respect a 95 W TDP limit out of the box, highly-threaded, demanding apps will run into this 95 W limit quickly, and boost clocks will drop to stay within the 95 W power envelope. This means that even when you choose to not overclock your processor at all, increasing the "Turbo TDP Limit" beyond 95 W, in line with what your motherboard VRM and cooler can handle, will instantly result in higher performance for these applications. In our testing with Blender rendering we could gain 15% performance just by upping the TDP limit, without any manual overclocking.
Intel Core i9 9900K review@Gouhan keenly awaiting your views on these CPU's.
I like the CPUs, in particular the 9900K and 9700K. Just the price is a sizeable jump from previous generations.@Gouhan keenly awaiting your views on these CPU's.
Thanks for the awesome review and honest feedback.I like the CPUs, in particular the 9900K and 9700K. Just the price is a sizeable jump from previous generations.
Intel's 14nm process has come a long way from Broadwell-E to what we have today.
This CPU is for the most part faster than the 7900X or 6950X which of course are 10 core parts with higher power demands.
9700K is the best as far as I'm concerned, the performance is still faster than what the 8700K offered despite the higher thread count advantage from the 8tth gen CPU. In fact because of the extra thermal headroom the 9700K over the 9900K, the overclocking tends to be a little more forgiving for airt/aio coolers. 5.2GHz 9700K is rather potent, beating the 9900K (default) at almost every turn.

Looking at your review of the 9900K for Nag, I'm pretty impressed, but a little surprised when I look at the Cinebench 15R graph. Timespy is questionable I'd say. When I ran my 2700X at 4.979ghz under DICE I got 2279 in cinebench 15R as can be seen here:NDA lifted.
I actually like this CPU.
Just be careful of some odd reviewer opinions which have little to no merit

Nothing regarding power changed form previous generations, literally nothing. Some settings and behaviours are board specific and not related to the CPU.
anyway will post my own numbers much later
Thanks for the feedback, I see other YouTube reviewers also debating this topic.Careful of some motherboards.
As you can see below, CPU hit it's power cap (95W, although I don't know why it capped here as the spec is Core power not total package power, but anyway).
Unsure as yet if such things can be fixed in the BIOS or at least to what extent. The board in question makes use of a rather weak voltage regulation complex. Basically, avoid cheaper Z390 boards if you're going for the 9900K CPU, should be ok with 9700K I didn't check and certainly fine with the 9600K.
I do understand a little though as this platform or this market segment was never dealing with loads upwards of 150W, that was always HEDT with appropriate power regulation and management for such loads. Some vendors may have just refreshed their low end Z270/Z370 boards without actually realising how much power the 9900K can consume.

The result looks very good.... Is this with the cpu running 6.7ghz.... and that multicore score for a 8 core 8 thread is insane.
There's no link to anything. DRAM was a random twp sticks picked from a tray of 50 pcs. ICs are newer Samsung B die.Can you tell me exactly what memory was used, please. Provide a link for it. Thanks

Buy which ever is cheaper.Im stuck between deciding on getting a i7-8700k or a i7-9700k.
