AMD Instinct MI100 vs AMD Radeon R5 M315: Comparison
What is the difference between Instinct MI100 and Radeon R5 M315?
Start with memory bus width, because it is the widest measured gap between them: Instinct MI100 4096 bit against Radeon R5 M315 64 bit, 98% in favour of Instinct MI100. Add boost clock to that, 1502 MHz on the Instinct MI100 versus 970 MHz on the Radeon R5 M315, and the pattern holds. There is a split on product type as well, Datacenter Accelerator on the Instinct MI100 versus Laptop GPU on the Radeon R5 M315. They differ on board partner too, Reference on the Instinct MI100 versus AMD on the Radeon R5 M315. There is a split on architecture as well, CDNA on the Instinct MI100 versus GCN on the Radeon R5 M315. They differ on shader units too, 7680 on the Instinct MI100 versus 320 on the Radeon R5 M315. Compute blocks is not the same on both, 120 on the Instinct MI100 versus 5 on the Radeon R5 M315.
Which should you buy, Instinct MI100 or Radeon R5 M315?
The Instinct MI100 suits buyers comparing AMD's official reference specifications and researching a chip before choosing a board-partner card, though it is not the pick for overclocking-focused enthusiasts (reference clocks only). It is not the one for buyers wanting a specific retail card with cooler and warranty details. The Radeon R5 M315 is the one to take for buyers comparing AMD's official reference specifications and researching a chip before choosing a board-partner card, though it is not built for overclocking-focused enthusiasts (reference clocks only). Avoid it for buyers wanting a specific retail card with cooler and warranty details.
