AMD Radeon RX 5300M vs AMD Radeon RX 5700M

AMD Radeon RX 5300M

The AMD Radeon RX 5300M is a dedicated mobile mid-range graphics card for laptops. It uses the new Navi 14 chip (RDNA architecture) which is produced in 7nm. Is supports fast and expensive GDDR6 VRAM and when using it, it should be faster than a GeForce GTX 1650 (according to leaked benchmarks from AMD).

The Navi 14 chip uses the new RDNA (Radeon DNA) microarchitecture which is a successor the the GCN instruction set. It features a new processor design, a multi-level cache hierarchy and an improved rendering pipeline with support for GDDR6 memory.

The performance should be around the GeForce GTX 1650 according to AMD. Therefore, it is most suited for medium to high detail settings in full HD for demanding games in 2019.

The RX5300M uses the same amount of compute cores as the faster 5500M but at a lower clock rate that leads to a lower TDP of the chip of 65 Watt (versus 85W of the 5500M).

AMD Radeon RX 5700M

The RX5700M is a mobile high-end graphics card for laptops. It uses the Navi 10 chip (like the desktop RX 5700 and 5700 XT) and therefore also the RDNA architecture. Like the desktop counterparts, the mobile RX 5700M uses dedicated GDDR6 graphics memory connected with a 256-bit bus. The performance is intended to be between the mobile RTX 2070 and RTX 2080 (3DMark 11 GPU score).

The Navi 10 chip uses the new RDNA (Radeon DNA) microarchitecture which is a successor the the GCN instruction set. It features a new processor design, a multi-level cache hierarchy and an improved rendering pipeline with support for GDDR6 memory.

The TDP of the chip is rated at 120 Watt and therefore clearly lower than the desktop RX 5700 (150 Watt) but clearly higher than the lower end RX 5500M (85 Watt). Therefore, the chip is intended for big gaming laptops.
