Test Setup and Overclocking

Intel 11th Gen Core i5-11600K and Core i9-11900K Review

Test Setup

We're utilising the ASUS ROG Maximus XIII Hero for our CPU tests today, although we're also testing a swathe of other motherboards should you want to see what else is in the Z590 range. Don't say we don't work hard to give you the best information from which to decide upon your next purchase.

Overclocking

The 11th Generation i5-11600K uses the familiar Intel Turbo Boost mode to push the processor hard when it has the spare capacity to do so, either in heat or power terms. The 11th Gen Core i9-11900K however uses a technology unique to this particular processor called Adaptive Boost Technology, or ABT. This takes into account the thermal headroom, power targets, core loading and the like to push the processor as hard as possible whenever possible. This is very similar to the AMD Precision Boost technology with similar results. It's refined enough that the gap between manually overclocking and letting the CPU/Z590 handle stuff is thin indeed, and all our tests today will be using ABT on the Core i9-11900K, and Turbo Boost 3.0 on the Core i5-11600K.

Well, 11600K looks fairly solid for gaming, if power efficiency isn't important. Looks to be as far as the architecture scales reasonably, more cores is pretty awkward thermals wise.


In fact 11600K is probably the go to CPU for gaming builds now, until AMD undercut it with a 5600 non-X. But I don't think they have the fabrication capacity.Quote

The i5 having stock is their only possible power move when AMD stock is quite hard to come by at the momentQuote

There seems to be plenty available in Finland currently, at MSRP. Which is a strange sight nowadays.
But seeing how Intel has their own fabs, not entirely unexpected.


Thanks for the reviews! That's a massive amount of benchmarks.Quote

Makes me feel good about my 5800X purchase a few days ago, Along with this review and a fair others today, Looks like both CPU manufacturers are about equal when it comes to gaming.Quote

Who would have thought Intel would have a Bulldozer moment Quote
