Intel Core i9-11900T pops up on Geekbench with UHD Graphics 750: Power-optimized Rocket Lake chip hits 4.89 GHz and floors the i9-10900T in single-core performance

A low-power Intel Core i9-11900T chip from the Rocket Lake family has appeared on Geekbench. The i9-11900T, which has an iGPU in the form of the UHD Graphics 750, recorded a clock rate of 4.89 GHz and produced an outstanding single-core score that was +26% over the Comet Lake i9-10900T.

Another Rocket Lake processor from Intel has been spotted on Geekbench by noted data-miner APISAK. The record reveals the i9-11900T, with the T-series units from Intel featuring lower TDPs but with a supposed minimum performance reduction when compared to non-T SKUs. This fearsome chip sped along at a maximum clock rate of 4.89 GHz (base: 1.51 GHz) with the help of an Asus ROG Maximus XIII Hero motherboard. Compared to the previous-generation i9-10900T, the clock range seems greater, with the older chip going from 1.9 GHz to 4.6 GHz (single core using Turbo Boost Max 3.0).

Although the i9-10900T is a 10-core, 20-thread processor, the 8-core, 16-thread Intel Core i9-11900T keeps up very well with its predecessor in the multi-core discipline. With a score of 8,349 points, there are only a handful of examples of the Comet Lake chip that surpass that result on Geekbench (71 samples at the time of writing). But the single-core result is where the news is at, with the Rocket Lake chip coming up with 1,717 points. This blasts anything recorded on the benchmark by the i9-10900T right out of the water. The highest score listed is 1,357 points, which leaves the i9-11900T over +26.5% ahead.

The Intel Core i9-11900T’s UHD Graphics 750 iGPU was also tested on Geekbench, churning out an OpenCL score of 7,761 points and revealing its 32 compute units and maximum frequency of 1.3 GHz. In comparison, the i9-10900T’s UHD Graphics 630 has 24 execution units and a boost rate of 1.05-1.25 GHz. The UHD 750’s score puts it over 52.5% ahead of the UHD 630’s average of 5,088 points. With an expected TDP of around 35 W, the Intel Core i9-11900T sample has given a demonstration of Rocket Lake’s generational improvements, especially in single-core processing, and hopefully at a reasonable power cost.
