![]() ![]() We cannot state any meaningful difference. Technically, we see a decline in these results, but they are mostly within error. Vega 56 showed a range of 0.17 from top-to-bottom of the averaged results in GFX 1, or 0.15FPS for GFX 2. Even overclocked and with a memory overclock, the difference between memory timings at stock and level 2 is effectively 0. These differences would be undetectable to a human. GFX 2 shows more meaningful gains if looked at from the perspective of error, but they are still meaningless to the user. Even if it does perform better than stock, though, the gains are irrelevant in this workload. We still can’t confidently state if the difference is statistically significant, but it does appear to have an uptick in performance. The The result of 66.03 follows the upward trend begun by timings level 1 and does exit deviation against stock even at the extremes, but only barely. Considering standard deviation is 0.22FPS for this test, this is not a meaningful difference. Memory timings level 1 puts GFX 1 at 65.83FPS AVG, a difference of +0.27FPS. GFX 2 will be the more accurate of the two numbers and should also be more sensitive to memory changes. Often the company that makes the card, but sometimes us (see article)Īfter running dozens of tests, we’ve found Firestrike to have a standard deviation of about 0.22FPS for GFX 1 and 0.06FPS for GFX 2.įor the Gigabyte RX 570 with stock timings, we measured GFX 1 at 65.56 FPS AVG across more than 10 test passes, with GFX 2 at 52.20. For now, we’ll focus on AMD’s built-in options. Were we to step it up, the next goal would be to use third-party tools to manually tune the memory timings, whether GDDR5 or HBM2, or custom VBIOSes on cards that are more stable. We also ran “real” gaming workloads in addition to these 3DMark passes. We ran an RX 570 and a Vega 56 card through most of our tests with these timings options, using dozens of test passes across the 3DMark suite (for each line item) to minimize the error margins and help narrow-in the range of statistically significant results. AMD’s GPU drivers have a drop-down option featuring “automatic,” “timing level 1,” and “timing level 2” settings for Radeon cards, all of which lack any formal definition within the drivers. Our card proved temperamental with the custom VBIOS, so we ended up instead – for now – testing AMD’s built-in timing level options in the drivers. This content piece started with Buildzoid’s suggestion for us to install a custom VBIOS on our RX 570 for timing tuning tests.
