UHD 770 Overview
With the release of Intel’s 12th generation of processors on November 4, 2021, 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 of the Alder Lake models only the i5-12600K, i7-12700K, and i9-12900K feature UHD 770 graphics. Meanwhile, Intel’s lower-end 12th-gen SKUs, the Core i3-12100 and Core i5-12400 surprisingly feature same UHD 730 graphics as the Core i5-11400.
The latest Raptor Lake 13th-gen Intel processor likewise employ UHD 770 integrated graphics, so the Core i5-13600K, Core i7-13700K, and Core i9-13900K are equipped with the same GPU as their most recent predecessors.
Boost Clock Variation Between Models
UHD 770 differs a bit from the 11th generation’s UHD 750 graphics in that there is some variation in clock speeds between models. Whereas all graphics-equipped 11th-gen CPUs, from the i5-11600K 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.
The UHD 770 GPUs packed into Intel’s newest 13th-gen Raptor Lake processors feature slightly faster boost clocks while retaining the same 300MHz base frequency: The Core i5-13600K has a max graphics dynamic frequency of 1.5GHz, the Core i5-13700K 1.6GHz, and the Core i9-13900K the maximum of 1.65GHz.
Even then, the Core i9-13900K’s pack-leading boost frequency is only 22.2% better than the lowest-end UHD 770-equipped Core i5-12600K. While this may seem like a sizable difference, the 12600K costs less than half of the 13900K.
What’s more, hardly anyone with the means to purchase an i9-13900K will be making use of integrated graphics, as they’ll almost certainly use a high-end 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).
UHD 770 Benchmarks
All UHD 770 benchmarks displayed directly below 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.
|Forza Horizon 4||31|
|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 over Intel’s 11th-gen, 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.
With graphics card prices close to normal in 2023, however, UHD 770 will more likely fill the traditional role of an integrated GPU, namely to provide a backup plan in case your video card dies suddenly. For this purpose it’s certainly adequate, but doesn’t offer much over older-gen Intel graphics like UHD 730 or UHD 750.
