UHD 770 Overview
With the release of Intel’s newest 12th generation of processors on November 4, consumers also gained access to Intel’s latest revision of integrated graphics, dubbed UHD 770. This is an upgrade over Rocket Lake’s UHD 750 graphics, which we reviewed and benchmarked earlier this year.
Intel only includes a functional GPU in non-F series CPUs, so at the moment only the Core i5-12600K, i7-12700K, and i9-12900K feature UHD 770 graphics. The next wave of 12th-gen processors set to release in early 2022, including the i5-12400, will presumably include this same iGPU.
Boost Clock Variation Between Models
UHD 770 differs a bit from last generation’s UHD 750 graphics in there is some variation in clock speeds between models. Whereas all graphics-equipped 11th-gen CPUs, from the i5-11400 to the i9-11900K had GPUs with the same 350MHz base and 1.3GHz boost frequencies, Alder Lake’s GPUs vary slightly in frequency. In other words, integrated graphics performance will vary slightly between lower and higher-end models.
How big will this difference be? Rather miniscule. While all three 12th-gen models have GPU base-clocks of 300MHz, the boost clocks of the i5-12600K, i7-12700K, and i9-12900K GPUs are 1.35 GHz, 1.4GHz, and 1.45 GHz, respectively. That’s a small 7.5% jump in performance from the Core i5-12600K to the top-of-the-line Core i9-12900K, for a rough 177% increase in cost.
What’s more, hardly anyone with the means to purchase an i9-12900K will be making use of integrated graphics, as they’ll almost certainly use a dedicated GPU. UHD 770 will therefore be most commonly used in the i5-12600K as a stop-gap GPU (for temporary use while waiting to upgrade to a discrete graphics card). It will be much more relevant when released in the Core i5-12400 in 2022.
UHD 770 Benchmarks
All benchmarks were recorded by Zax Game Inn on the lowest in-game settings in 1080p on the Core i5-12600K. Thus, figures for the i7-12700K or i9-12900K can be expected to be marginally higher.

|Fortnite (Performance Mode)||125|
UHD 750 vs. UHD 770
While UHD 770 certainly improves upon its predecessor, it doesn’t do so by enough of a margin to ensure 60FPS in the majority of AAA games, which would be ideal. In-game framerates recorded by Benchmark Lab give us these results:
|Game||UHD 750 Avg. FPS||UHD 770 Avg. FPS||UHD 770 Margin of Advantage|
|Hitman 3 (1280x720 Low Settings)||30||35||+16.7%|
|Red Dead Redemption 2 (1280x720 Low Settings)||25||31||+24%|
|CS:GO (1920x1080 Low Settings)||135||146||8.1%|
|Fortnite Performance Mode (1920x1080 Low Settings)||90||105||16.7%|
|Witcher 3 (1280x720 Low Settings)||32||36||12.5%|
|Horizon Zero Dawn (1280x720 Low Settings)||24||27||12.5%|
Overall, then, UHD 770 graphics outperformed UHD 750 by an average of 15%. While they’re markedly better, they fail to achieve the desired 60FPS minimum in many AAA titles.
UHD 770 vs. Vega 11
Next, we’ll compare UHD 770 graphics to AMD’s competing Vega graphics, those of the Ryzen 5 3400G. It’s worth noting that the newer Ryzen 5 5600G and Ryzen 7 5700G will perform similarly to the 3400G.
|Game||UHD 770 Avg. FPS||Vega 11 Avg. FPS||Vega 11 Margin of Advantage|
|Hitman 3 (1280x720 Low Settings)||35||40||+14.3%|
|Red Dead Redemption 2 (1280x720 Low Settings)||31||36||+16.1%|
|CS:GO (1920x1080 Low Settings)||146||164||+12.3%|
|Fortnite Performance Mode (1920x1080 Low Settings)||106||123||+16%|
|Witcher 3 (1280x720 Low Settings)||36||40||+11.1%|
|Horizon Zero Dawn (1280x720 Low Settings)||27||33||+22.2%|
Despite Alder Lake’s graphical improvement, AMD’s APUs still best Intel’s by an impressive average of 15.3%.
There’s no doubt that Intel’s integrated graphics have improved since last generation, but even so UHD 770 graphics aren’t enough to warrant a purchase in and of themselves. Unless you’re content running games at sub-60 frames per second, you’d do a lot better opting for one of AMD’s APUs like the Ryzen 5 3400G, Ryzen 5 5600G or Ryzen 7 5700G if you simply can’t find an affordable graphics card.
