In the previous video we seen the R9 280X take on the Tonga based R9 285 and put it to the sword. Today we are going to give the R9 280X a little bit of a harder challenge… The real Mcoy of the Gen 3 mid range, the R9 380X.
While the R9 285 was a sort of half way house, the R9 380X is really the direct replacement for the 280X Both cards feature 2,048 shader units, 128 TMU’s and 36 ROPS with the 280X being GCN gen 1 and the 380X built on GCN gen 3
Spec wise the main differential is the memory configuration. We all know and love the 280X’s 3GB GDDR5 sitting on that 384-bit memory bus and the 380X gives and takes away in the same swipe. The 380X adds and extra 1GB of GDDR5 taking the total up to 4GB - plenty for a mid range card in 2018, but still uses the 256-bit memory bus of the R9 285. This means there is a memory bandwidth of 288GB/s on the 280X and 182GB/s on the 380X quite the difference
The R9 380X was tested at stock configuration for this Sapphire Nitro model which is 1040 on the core and 1500 on the memory - one of the faster variants available for those wondering. For completeness, the 380X has also been overclocked to 1100Mhz on the core and 1,500Mhz on the vram which was the same as the max OC i could manage with this VTX version of the 280X The 380X also had a little more headroom and could be pushed to 1,125 Mhz on the core and 1,600 Mhz on the Vram which i've included.
We will be running these tests on the Budget AM4 test bench which consists of a quad core Ryzen 5 1400, 8Gb DDR4 3000 memory and we have locked the CPU clock speed to 3.7Ghz on all 4 cores.
This is going to be a close one, in my opinion both are great budget options… but which one will come out on top!!?
