If you want to read our discussion on what Intel’s TDP values actually mean, here’s a handy guide we wrote late last year. Intel did give us all-core ratios for AVX2 and AVX512 as well, at 3.2 GHz and 2.8 GHz respectively, however the ASUS motherboard we used had other ideas, setting these values at 3.5 GHz and 3.4 GHz which it said was ‘Intel POR (specification)’. With these big chips, usually a system needs a few cores or all the cores, so expect to sit around 4.0-3.8 GHz most of the time. That frequency is kept all the way until >24 cores are loaded, where it sits at 3.8 GHz. The top 4.3 GHz turbo frequency is 4.3 GHz, which within eight cores goes down to 4.0 GHz. As a result, we have the following turbo values: Intel Per Core Turbo Values (SSE) They used to give this information out freely, but in recent consumer launches no longer offer this info, despite it being available directly from the chip if you have one to put in a system. Per Core TurbosĪs always with new Intel processors, we ask the company how the turbo ratios change as more cores are loaded. This is only a limit though – processors can (and have) run well below this power limit, so we actually need to do some testing.
#Intel power gadget review full
Normally Intel sets the PL2 at only 25% higher, but this time around, it’s a full 100% higher. Intel defines two power limits for this processor: the PL1 or ‘sustained’ power limit, at 255W, and a PL2 or ‘turbo’ power limit at 510W. Speaking with Intel before this review, they gave us two numbers of ‘power limits’. Just don’t ignore the fact that it has a 3.8 GHz all-core turbo frequency, which will push that 255W TDP through the roof. That makes it Intel’s highest TDP chip for a non-server focused processor. Then later in the year, Intel declared that the newly named Xeon W-3175X would be rated at 3.1 GHz for a 255W TDP. Even at that point, people were wondering exactly how much power this CPU would put out. When Intel did a little demo at Computex 2018, with 28 cores all running at 5.0 GHz, we eventually found out that the system needed a 1700W water chiller to stay cool.
