Intel UHD Graphics Xe 750 32EUs (Rocket Lake) vs NVIDIA GeForce RTX 3050 6GB Laptop GPU vs Intel Iris Xe Graphics G7 80EUs

The Intel UHD Graphics Xe 750 (Rocket-Lake GPU with 32 EUs) is a integrated graphics card in the high end Rocket-Lake CPUs. It is using the new Xe architecture (Gen12) and was announced in March 2021.

Compared to the previous generation of UHD Graphics ,the Xe architecture and the improved shader count lead to a big leap in graphics performance. Still, the UHD 750 is only suited for low demanding games or very low settings. The 48 EU version in Tiger Lake SoCs e.g. reached 46 fps in The Witcher 3 low 1024x768 and no fluent framerates in Mafia Definitive Edition.

The Rocket Lake SoCs and therefore the integrated GPU are manufactured in the old 14nm+++ process at Intel.

The Nvidia GeForce RTX 3050 6GB Laptop GPU (mobile, GN20-P0-R, 2023 Refresh) is the refresh of the RTX 3050 4GB Laptop GPU (slowest RTX 3000 mobile card) and also based on the GA107 Ampere chip. The 6GB variant offers more CUDA cores (2,560, +25%) but a cut down memory bus to 96 Bit. The clock speed depends on the TGP variant and can range from 713 - 1530 (base) and 1058 - 1740 (boost) for the TGP variants of 35 to 80 Watt (see table below).

The performance is between the old 4GB RTX 3050 and the RTX 3050 Ti and therefore best suited for full HD gaming (1920 x 1080) in medium to high graphic settings. The performance is not sufficient to enable Raytracing in most games, but the Tensor cores can be used for DLSS in some games (and get performance boost with slight quality reduction). Beware, that the low TGP variants will offer a significantly lower performance.

The GA107 chip offers 3,072 FP32 ALUs of which half can also execute INT32 instructions (i.e. 1,536 INT32 ALUs). The RTX 3050 however maybe won't use all ALUs on the chip. With Turing all shaders could still execute FP32 or INT32 instructions. The raytracing and tensor cores on the chip were also improved according to Nvidia. The Ampere chips also include an improved 5th generation video encoder (NVENC for H.264 and H.265) and a 7th generation decoder (for various formats now including AV1).

The GA107 chip is manufactured by Samsung in 8nm (8N), which is not quite able to keep up with the 7nm node at TSMC (e.g. used by AMD and also for the professional GA100 Ampere chip).

The Intel Xe Graphics G7 80EUs (Tiger-Lake U GPU with 80 EUs) is a integrated graphics card in the mid range Tiger-Lake U CPUs (15 - 28 Watt, e.g. Core i5 11th Gen CPUs). It is using the new Xe architecture (Gen12) and should be announced later in 2020.

The performance depends on the TDP settings of the laptop and the used cooling. First informations show that the chip can be configured at 15 and 28 Watt TDP default (as the Ice Lake-U chips) and the performance should be around a dedicated GeForce MX330 in 3DMark benchmarks. For gaming we are expecting a bit worse performance due to the missing dedicated graphics memory and driver support. Compared to the older Iris Plus G4 in Ice Lake chips, the Tiger Lake GPU should be nearly twice as fast. Benchmarks with various laptops show that the 80EU version lacks about 18% behind the faster 96EU version and on par with the MX330. Compared to AMD iGPUs, the G7 80EU positions itself around the Vega 7 and Vega 8 chips (see chart below for details).

Therefore, the iGPU is still only for lowest graphical settings and low resolutions in demanding games. Some modern games like Days Gone or Cyberpunk wont run over 30 fps in minimum settings (see below).

The Tiger Lake SoCs and therefore the integrated GPU are manufactured in the modern 10nm+ (10nm Superfin) process (improved 10nm process) at Intel and therefore should offer a very good efficiency.
