AMD Radeon RX Vega 11 vs AMD Radeon RX 570 (Desktop) vs AMD Radeon RX Vega Mobile

AMD Radeon RX Vega 11

The AMD Radeon RX Vega 11 is an integrated GPU in the Ryzen desktop APUs (e.g. Ryzen 5 2400G) that were launched early 2018. The graphics card is based on the Vega architecture (5th generation GCN) and has all 11 CUs (=704 shaders) clocked at up to 1240 MHz (Ryzen 5 2400G). The GPU benefits from fast dual-channel DDR4-2400 RAM (contrary to DDR4-2133 single-channel, which is also possible).

The Vega architecture offers some improvements over the Polaris generation and now supports DirectX 12 Feature Level 12_1. More information is available in our dedicated article about the Raven Ridge architecture.

According to a first 3DMark Fire Strike that was published by AMD, the Vega 11 offers a similiar theoretical performance as the older dedicated Radeon R9 M280X. In games the missing dedicated graphics memory may however prove to be a bottleneck. Therefore, modern and demanding games will only be playable in lowest settings and the APU is mostly intended for lower demanding games like Overwatch, Dota 2, ...

Thanks to the 14nm process and clever power-saving features, the power consumption is comparatively low. The high TDP of 65 Watt of the APU however should lead to a much higher power consumption compared to the mobile APUs with 15 Watt TDP.

AMD Radeon RX 570 (Desktop)

The AMD Radeon RX 570 is a mainstream graphics card for desktop PCs. It was announced in April 2017 and is based on the Polaris 20 chip. It is a refresh of the RX 470 and uses the same chip as the RX 580 (and 580X) with less shaders. The clock speeds are specified as 1,168 - 1,244 (Boost). The VRAM is connected by a 256 Bit bus and clocks at 1,750 MHz (effective 7,000 MHz) which leads to a 224 GB/s memory bandwidth.

At launch, the performance of the Radeon RX 570 was slightly below a Nvidia GeForce GTX 1060. Therefore, the GPU is best used for 1920x1080 and high detail settings for demanding games of 2019.

The TDP of the Radeon RX 570 is specified with 120 Watts by AMD, so a single 6-pin power connector is sufficient.

AMD Radeon RX Vega Mobile

The AMD Radeon Vega Mobile is a dedicated graphics card for laptops. It most likely uses the same chip as the Kaby-Lake-G graphics part. Rumors currently speak of 28 CUs (= 1792 shaders) instead of the 24 CUs in the Kaby-Lake-G top model. The clock speed should be also around 1 GHz. As graphics memory, the GPU most likely also uses 4 GB HMB2.

The Vega architecture offers some improvements over the Polaris generation and now supports DirectX 12 Feature Level 12_1. More information is available in our dedicated article about the Raven Ridge architecture.

The power consumption should be similar to the Kaby-Lake-G chips (altough this may be more efficient due to power sharing and distribution). The Kaby-Lake-G is rated at 100 Watt including a 35-45 Watt processor.

The Radeon Vega Mobile was announced one day before CES at a press event by Lisa Su.
