Title: Uncommon Core i9-9900T requires no active cooling, offers similar multi-thread performance to the Core i7-9750H
Post by: Redaktion on April 11, 2020, 04:26:54
The 8-core 35 W Core i9-9900T can stand neck-to-neck with a 45 W Core i7-9750H with nothing more than just a large heat sink... for a set amount of time, at least.

future is this! max 65-75W of TDP with good performances.

So basically it's an octa core desktop chip on par with a hexa core laptop chip. Gotta love Intel.

Power matters greatly. Desktop or laptop doesn't matter much. Laptops don't exist in an alternate universe with different laws of physics. And if a so called laptop chip can potentially take 90 W if not more, it really blurs the line, doesn't it. Cooling is a huge limiting factor (electric power has to turn into something - heat, sound, light; processors don't make much noise and they don't glow much either). And fully passive cooling, especially in a sealed chassis, is quite challenging. Anyway, it's a quite well known fact that from some point, increase in frequency leads to decrease in efficiency. So, for given amount of power (heat), higher core count chip should offer better performance (or, eat less power for the same performance), up to a point. Assuming your workload can scale out as well as up. Today, desktop processors have a lot of the features that were pioneered for laptops. The big difference is that a desktop can easily have beefy cooling and there is no battery to worry about which allows you to pump a lot more power into the processor. Without the cooling advantage, there is no reason a desktop chip should be better; if anything, the opposite (if there is a difference, you'd expect the laptop processor to be better at low power operation as that's bread and butter for laptops).
