Seems like it's hard to cool GPUs in desktops too if you're Apple >their maximum FP32 compute performance is 11 TFLOPS (which points to around 1340 MHz clock-rate for the Vega 64) and their peak memory bandwidth is 400 GB/s (indicating about 1600 MT/s memory speed), which is slower when compared to the Radeon RX Vega cards for desktops. The main reasons why Apple downlocks its GPUs are of course power consumption and heat dissipation https://www.anandtech.com/show/12152/apple-starts-imac-pro-sales-on-dec-14 https://www.anandtech.com/show/12152/apple-starts-imac-pro-s... Sad to see that this is becoming a recurring theme from Apple's pro line.

Dont have to be cool, if the cult got the hots for you.

Downclocking, by itself, tends to increase component lifetime. It makes sense for a professional machine that's not supposed to break after a couple years. Of course, if the component still overheats, that completely beats the purpose of the downclocking.

  Exactly. In other tech this is called headroom. It’s just a pragmatic approach to a physical limitation. The right choice given the clientele— debatable. But just the same it’s not unique to computer manufacturers.

  Or, they've gotten a really good deal on binned chips.
