![]() For the 4790K, that's the factory-shipped four-core Turbo Boost setting. I took the Core i7-4770K and -4790K, dropped them both into MSI's Z97 Gaming 7 motherboard, applied the same 1.275 V, and manually dialed in a 4.2 GHz clock rate. With the changes mentioned above, I gave it a much shorter cap. Before I applied these changes, my CPU was basically drawing power for the sake of drawing power and thus created lots and lots of heat. The Impact Of Intel's NGPTIMīefore we get to the bulk of our numbers, I wanted to isolate the impact of Intel's Next-Generation Polymer Thermal Interface Material. This item Intel Core i7-4790K Processor (8M Cache, up to 4.40 GHz) BX80646I74790K Intel Core i7-12700K Desktop Processor 12 (8P+4E) Cores up to 5. Turbo Boost Power Time Window: 8 Seconds. ![]() Throughout the testing, you’ll see our stock and overclocked performance results at sustainable clock rates, representing a range of frequencies based on the test being run. A Prime95 burn-in might have been more troublesome, but the benchmarks we ran weren’t limited by the temperatures we were seeing. Rather than slamming into a throttling condition (usually brought on by too much voltage triggering untenable temperatures), we ran into the sort of crashes you can typically stave off by supplying more power to the CPU. ![]() ![]() Most notable, perhaps, is that the Core i7-4790K doesn’t seem to suffer from the same quick saturation of heat that our 4770K samples experience.
