We’re testing the gaming performance of the internal Iris Xe GPU on Intel’s Tiger-Lake U Core i7-1165G7 processor.
Intel Iris Xe Graphics G7 (GPU with 96 execution units) is an integrated graphics processor found in high-end Tiger-Lake U CPUs (15-28 Watt). This GPU uses the new Xe architecture (Gen12) introduced in September 2020. The GPU can go up to 1340 MHz (i7-1185G7) in the Boost frequency while running at 400 Mhz base clock frequency (guaranteed) on all processors. The slowest version offers only 1100 MHz Boost (i5-1130G7, 12 Watt TDP) frequency.
On Tiger Lake-U processors – or rather, in most mobile processors in general – the performance depends on the TDP settings of the laptop and the cooling used. We know that the chip can be configured at 12 and 28 Watt TDP by default (as Ice Lake-U chips) and the performance is around the GeForce MX350 in 3DMark tests. On the other hand, when it comes to games, we can expect the GPU to give a slightly lower performance due to the lack of dedicated memory and driver support. Of course, compared to the old Ice Lake Iris Plus G7 GPU, the new Tiger Lake GPU is about twice as fast. Therefore, the iGPU is still suitable for demanding games only for the lowest graphics settings and low resolutions, which our tests confirm.
Tiger Lake SoCs, and hence the integrated GPU, are Intel’s modern 10nm + (10nm SuperFin) (enhanced 10nm process) and therefore offers a very good efficiency. So what about efficiency when it comes to game performance? Here is Iris Xe gaming performance with four different productions:
Intel Iris Xe Gaming Test
|Game||Resolution and Setting||FPS|
|World of Tanks||1080p
|Mount & Blade II Bannerlord||1080p
- Operating System: Windows 10 Pro 64-bit 20H2
- System Model: ZenBook UX371
- Processor: 11th Gen Intel Core i7-1165G7 @ 2.80GHz (8 CPUs), ~ 2.8GHz
- RAM: 16 GB
- GPU: Intel Iris Xe Graphics
First of all, we were surprised that the GPU saw 120 FPS in CS: GO. Here you can connect a 120 Hz monitor to your laptop and play CS: GO, but competitive gameplay is a bit difficult because a lot of values such as lag are involved and this is where iGPU fails. Since FPS drops to extremely low levels in places, stuttering may occur.
Iris Xe also managed to surprise us by reaching almost 60 FPS in Mount & Blade II Bannerlord. On the other hand, it has dropped to 0.1% FPS 3 here too, which can undermine your gaming enjoyment. PUBG and World of Tanks are not playable with an average of 25 and 33 frames. As a result, although we appreciate Intel’s efforts to increase the performance of its internal GPUs, it is worth noting that the performance is still not at the desired level.
