## Description

From the manufacturer

Review: Personal preference paid off - Don't Worry when you watch you tube reviews; half of them take with a pinch of Salt. This Processor works well with intel's Super Boost that pretty much takes care of half the Bios settings, RAM running well CUDIMM @ 8000mts without issues. For Casual Gaming and other tasks fitted with a Crucial T705 its very fast, not had any heat issues or heat related Thermal throttles causing any Stutters, it Works well. High FPS on a 165Hrz 4k Monitor as expected, yes AMD can have an uplift in FPS so it Can be that team RED or Blue divide. Personally Heat, Power and reliability from this Core Ultra 9 is worth a loss of 10/20 fps in games. The Margin of AMD tends to Greater in 1440p. All-rounder PC then this is the Processor to buy it also has NPU, Future AI stuff. Early setups will potentially have issues if not updated to Manufacturer latest BIOS and Micro codes from INTEL. New Builds have these to hand, update the bios from flash drive prior to Windows install. less issues. Intel is releasing a refresh model prior to a new processor and chip set that is going to increase Gaming speeds but this Core 2 Ultra 9 if picked up at the right price should last for years. Half of the review for this are well out of date and Intel has done some wizardry to get it up to speed.
Review: An impressive CPU for gaming and rendering - This CPU has greatly increased my productivity, it's speed and power is perfect for both heavy gaming and 3D rendering. I haven't had any stability issues with this CPU, and although anecdotal, neither has my friend with the same chip. Whilst very expensive, it doesn't feel quite as painful to the wallet purely because of how capable it has been. It does however need some beefy cooling. I use a Noctua Nh-u12a chromax cooler and sit at about 36° at idle, and push 65° to 70° under normal gaming usage; under heavy rendering it can reach 80° but it hasn't seemed to have throttled itself to intensely because of it. Pros: Great stability Fantasftic power Wide range of functionality Cons: Pricey Requires good cooling

### ⭐⭐⭐⭐⭐ Awesome chip for productivity.
*by J***S on 11 February 2026*

Productivity first, gaming second. Ignore people who keep comparing this to gaming chips, it's a productivity chip which is very good at gaming too. Nothing compares to it for productivity though.
