The Intel’s own Xe GPU inside the upcoming Tiger Lake APUs could offer a tough competition to ZEN 2-based AMD Ryzen Renoir 4000 Series of APUs with onboard Vega graphics. A leaked benchmark indicates the Intel Gen12 iGPU can go up a lot during an on-demand performance boost.
Intel’s Tiger Lake APUs are expected to be officially announced soon. They will arrive in multiple TDP profiles for various mobile computing devices and form-factors. However, the first ones to arrive will be intended for powerful gaming and performance-centric laptops. More importantly, these new generation APUs will reportedly offer a 2x performance uplift compared to the previous generation Iris GPUs featured on Ice Lake CPUs.
Leaked SiSoftware Benchmark Database Shows An Impressive 1650 MHz Overclock Of Intel Iris Xe GPU:
Intel has been readying multiple variants of the Xe GPU, including the DG1, Iris, HPC, HPG, and a few more. These GPUs are meant for different purposes and form-factors. Consumers, however, will be interested in the Xe Iris GPU and the Xe DG1.
The Iris Xe GPU is a little different than the DG1 GPU. The main difference is that the Xe DG1 is a standalone discrete GPU while the Iris Xe GPU is an integrated unit on the Tiger Lake CPUs. Both chips do share some similarities as they both peak out at 96 EUs (Execution Units) which translates to 768 cores.

The Intel Iris Xe GPU, in its fastest stock configuration, will feature a clock speed of 1300 MHz. The Intel Xe DG1 GPU has been clocked at up to 1550 MHz. The leaked SiSoftware Benchmark Database entry for the Intel Iris Xe GPU shows it is running at 1650 MHz which is a 27 percent overclock over the reference clock speeds.
The Gen12 Xe Iris iGPU was running on a Tiger Lake 28W CPU. The Tiger Lake G7 variants feature the same core and clock speeds of 768 and 1300 MHz, respectively. It is not immediately clear which particular Tiger Lake APU variant the Xe GPU was running on.
Can Intel Tiger Lake APUs With Xe Iris iGPU Challenge The AMD Renoir Ryzen 4000 Series With Vega Graphics?
The Vega GPU featured on the ZEN 2 based AMD Renoir Ryzen 4000 Series APUs clocks up to 2100 MHz. However, it can be overclocked up to 2300-2400 MHz which is about a 10-15 percent jump. Although the boost in terms of percentage is low, the Vega iGPU is more powerful, to begin with. Still, the Vega GPU features lower cores than Intel’s Iris Xe GPUs.

Interestingly, the performance of the Gen12 Intel Xe Iris iGPU should translate to roughly 2.5 TFLOPs. These numbers indicate it is faster than both the currently available dedicated gaming consoles; the PS4 and Xbox One. Experts claim the performance will also be faster than the desktop Ryzen 7 4750G which features around 2.15 TFLOPs performance at the stock 2.1 GHz clock speed.
With these numbers, the Iris Xe GPU can easily outperform a desktop-grade dedicated NVIDIA GeForce GTX 1050 Ti Graphics Card or the AMD Radeon RX 5300M mobility or discrete GPU. If that’s not enough, the discrete GPU working inside the Intel Core i7-1185G7 is reportedly as fast as the Radeon Pro 5300M.
