I graphed normalized benchmark data as well as performance per dollar for both AMD & Nvidia cards

I’ve been seeing a lot of back and forth on both AMD and Nvidia subreddits about reviewers lying about results, omitting specific tests, 3DMark not properly implementing DX12. and on and on…

As for me, I like numbers and graphs. I’d say numbers don’t lie…but that would be a lie in itself, so I’ve done my best to come up with a representation of neutral benchmarks that can be agreed upon as unbiased by both sides.

I used benchmark results from Guru3D, and then normalized them, interpreting results as a % of a specific card’s performance, as opposed to using the raw FPS numbers, which can throw off the average by overly favoring games with high framerates. I used the RX 480 as the benchmark 1080p card, and the GTX 1080 as the benchmark for 1440p and 4K resolutions.

I then grabbed the lowest price for each card that I could find on Newegg (not using Open Box prices, of course) to get a number for performance per dollar (NOT FPS/$, since I’m using normalized data).

The result is, I hope, a fairly unbiased report on the performance delta between cards, averaged over many games, as well as a report on which cards will deliver the biggest bang for your buck. Additionally, I included two graphs which ONLY factor in DX12 games, since some would argue that these will matter more in the coming years. Keep in mind, though, that there are only 4 DX12 games in the benchmarks, so this isn’t what I would call a suitable sample size yet.

Without further ado, here are the graphs:


Some Notes:

  • I did not include Time Spy benchmarks in the results. I typically do not give much weight to synthetic benchmarks when GPU shopping, and I didn’t want to deal with the headache of debating whether it represents a real DX12 test or not.
  • I have included a dropbox link to the spreadsheet where I entered in all the numbers and created the graphs for anyone who feels like diving in to the numbers or tweaking the graphs to show some other aspect I didn’t include.
  • These graphs represent cards at their factory clocks and lowest prices. These will obviously be affected by 3rd-party boards and factory overclocks, but I believe this to be a good starting point and I don’t think the results will be TOO shaken up by this.


I hope this proves useful to some of you who may be shopping or just curious, and as always I look forward to your thoughts and suggestions.


EDIT #1: It’s been pointed out to me that my performance-per-dollar metric is for the 8GB RX 480 and not the 4GB model. This is true, and is because literally EVERY review I have read has used the 8GB model. That said, the 4GB model should have equivalent performance (perhaps +/- 1 fps) at most at all 1080p resolutions, since no game is currently approaching 4GB of texture usage at that resolution. Given that information, I’ve created a new 1080p performance per dollar graph, with the 4GB RX 480 included. This is ONLY for 1080p as I don’t feel comfortable assuming equivalent performance at higher resolutions until I see a review by a website I trust. Again, this is a graph based on the assumption that the 4GB model will perform the same as the 8GB model, something I’m confident in based on past performance of 4GB/8GB models, but which I haven’t seen proven. As such, this graph will only be included down here as an addendum and not with my main graphs. Hopefully, this doesn’t cause too much backlash…

EDIT #2: I’ve used Anandtech’s RX 480 review to calculate the performance delta between the 4GB and 8GB models at 1080p and 1440p (96.7% of the RX 480 and 97.0%, respectively). I have updated the 1080p and 1440p charts to include the 4GB RX 480 model and it’s performance per dollar metric, and I have also re-normalized the 1440p and 4K charts for consistency, and all 3 now use the RX 480 as the baseline and the spreadsheet has been updated as well. For those of you mentioning the Furys‘ new, lower prices, I’m aware of those, but they won’t be changed in the spreadsheet or charts until those pricing changes are reflected on Newegg, again, for consistency so that all part prices come from the same source. Other users are more than welcome to tweak my graphs and reupload with their own pricing info.
