The WX2100 and RX 540 are both GCN 4 Polaris 12 (Lexa), but the RX has twice the memory bandwith. So the WX2100 is slower, but in normal use draws about half the power of the RX. So its a nice choice for cramped boxes when users just need something better than integrated. The embedded marketed version of the WX2100 is the e9173, which is pretty much the same thing, but with a black motif on the shroud and graphics.Eh, no. The WX2100 will be more powerful (that’s what, like an RX540?). This is GCN2, so this is more like a Radeon R5 M230 sliced in half.
Per the datasheets I found online, Fujitsu offered the FirePro W2100 with the S920 that @Samir linked. W2100 is actually GCN1and was seriously gimped to keep the heat down. On the other hand, if you need a GPU that pulls less than 25w even when its maxed out, this one is for you!
