AMD Radeon RX 5300M vs AMD Radeon RX 6300M vs AMD Radeon RX 6800S

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 6300M

The AMD Radeon RX 6300M is a mobile entry-level graphics card based on the Navi 24 chip (RDNA 2  architecture) manufactured in the modern 6nm process. It features 768 cores (12 CUs - compute units) and 2 GB of fast GDDR6 graphics memory connected with a 128 Bit memory bus. The chip also includes 8 MB Infinity Cache. The game clock speed is specified at 1512 MHz. The 6300M supports Smart Access Memory and SmartShift Technology.

The performance should be similar to a mobile GTX 1650 (according to AMD) and therefore best suited for 1080p gaming with medium settings.

The Navi 24 chip is manufactured at TSMC in the modern 6nm process and should offer a good energy efficiency.

AMD Radeon RX 6800S

The AMD Radeon RX 6800S is a mobile high-end graphics card for gaming laptops. It uses the Navi 23 chip based on the new RDNA 2 architecture. It uses all 2,048 shaders (= 32 CUs), 128 TMUs, and 64 ROPs and therefore is similar to the desktop Radeon RX 6700 XT. The 128 Bit memory system connects 8 GB GDDR6 with 2 GHz memory clock. Furthermore, the RX6800S includes 32 MB Infinity Cache. The RX 6800S is the power saving variant of the RX 6800M and features slower clock speeds and a lower TDP.

Due to the lower clock speed, the performance should be lower than the RX 6800M. AMD specified the performance between the low power variants of the RTX 3070 (80-100W) and RTX 3080 (80-100W, former Max-Q).

The Navi 22 chip is manufactured at TSMC in the modern 7nm process. Thanks to the reduced TDP, the 6800S is suited for thin gaming laptops.
