Title: Quad-core Core i7-8650U CPU spotted on GFXBench
Post by: Redaktion on May 06, 2017, 08:01:37
Intel may be bringing quad-core ULV CPUs to notebooks for the first time. The source has since taken down the listing on the unconfirmed processor page to add more fuel to the fire.

It seems hilarious. I don't understand target customer group . Quadcore is meaningful for users who need long duration maximal performance above Turbo limits ( above 5 minutes). For short duration performance tasks it doesn't matter if the tasks is 2times slower ( Amdahl's law ignored).

If the ULV quadcore will throttle after minute, it would be useless. I don't think 8000 CPU series will be so extremely efficient that they would fit into 15W TDP. Or will there be TDP up magic? Like 6xx7U (TDP 28W, TDP up 35W)

Correct? Is there such usage scenario.

Who is target consumer for this? Maybe people who need laptops with portability AND perfomance? How many laptops do you know with quad core CPUs that have both big batteries and low power consumption? I know NONE. So far, the only laptops with quad core processors(like dell xps 15) needed to have huge batteries in them in order to have battery life comparable to laptops with ulv dual cores. With ULV quad core cpu-s a user would have both excellent perfomance(I think on the level of quad core laptop i5-s right now) and great battery life. And no, most of ulv processors don't thottle due to low tdp. My i7 6500u stays at it's maxmum 3ghz for both cores no matter how long I push it to 100%(I convert a whole tv show to hevc h265 for weeks now and it hasn't throttled since).

the i7 will have 25w tdp up when plug in. This thing could work, I will wait to see benchmarks if is worth upgrade from mine i7 6500u laptop
