Radeon RX 460 graphics card has more Stream Processors than what AMD lists

AMD released its Radeon RX 400 Series graphics cards earlier this summer, based on its new “Polaris” graphics chip design. Aimed at the general consumer wanting to update their PC’s graphics on the cheap, the company launched the Radeon RX 480 first as the “flagship” performance model of the series followed by the RX 470 and RX 460 shortly after that. The RX 460 is the cheapest and the slowest performance-wise compared to its two siblings, but now RX 460 owners can squeeze more speed out of the card thanks to a modified BIOS file.

Overclocking.Guide discovered over the weekend that the RX 460 actually contains 1,024 Stream Processors instead of the listed 896. When the remaining Stream Processors are enabled using a modified BIOS file, owners can see an increase in performance of up to 12.5 percent. So far there’s no indication of why AMD chose to lock away the 128 hidden cores, but the company may have discovered that the card was growing too hot using all 1,024. It’s really anyone’s guess at the moment.

Regardless, the extra cores are there and Overclocking.Guide is currently providing an edited BIOS for the Sapphire Nitro 4G and the Asus Strix O4G. Overall, the site tested six Radeon RX 460 cards provided by Sapphire and Asus, five of which were the Strix O4G, all of which were fully capable of unlocking the 128 hidden GPU cores. The site plans to upload additional modified BIOS versions for other RX 460 cards in the near future.

First, here are the updated BIOS downloads:

  • Asus RX 460 Strix O4G Unlocked BIOS (290.84 KB)
  • Sapphire RX 460 Nitro 4G Unlocked BIOS (290.67 KB)

Next, for those planning to use the modified BIOS, be sure to backup the card’s original BIOS file just in case something goes wrong or if users simply want to revert back to the original settings. After all, the cores were locked away for a reason, so backup just in case. To do this, either run the included “backup bios.bat” file, or use the latest version of GPU-Z from TechPowerUp to save the original BIOS file. After that, run the “flash unlocked bios.bat” file to install the modified BIOS. Reboot the PC when completed.

The site performed several benchmarks comparing the performance of the original BIOS file to the modified file unlocking the hidden cores. Here are the results:

Sapphire RX 460
Nitro 4G
Stock BIOS File Unlocked BIOS File Performance Gain
3Dmark FireStrike GT1 2775 3018 +9 percent
The Witcher 3 (Max FPS) 3533 3700 +5 percent
Asus RX 460
Strix O4G
Stock BIOS File Unlocked BIOS File Performance Gain
3Dmark FireStrike GT1 2735 2919 +7 percent
The Witcher 3 (Max FPS) 3433 3733 +9 percent

The site notes that the modified BIOS files were tested with the Radeon Crimson Edition 16.11.5 driver, and there’s a good chance the new Crimson ReLive Edition driver won’t work on cards with a modified BIOS file given the driver requires a verified BIOS signature. There is a workaround on TechPowerUp’s site here just in case.

Finally, users may also need to delete the card in Device Manager and restart the PC before installing the latest driver with the modified BIOS file intact.

Lenovo ThinkStations desktops are 50% off right now
The Lenovo ThinkStation P3 Tiny Workstation, lying flat on its side.

We'll go into all the details below, but if you want to check out the machine for yourself, go ahead and tap the button below to find the desktop over on Lenovo, where it is part of one of their Doorbuster deals. It's currently just $879, which is $880 off the usual $1,759.

Why you should buy the Lenovo ThinkStation P3 Tiny WorkStation
When evaluating a prebuilt PC, you should think of how its going to be used and work up from there. So, you might want to consider what situation you'd use the Lenovo ThinkStation P3 Tiny WorkStation in before anything else. It's body is in a smaller than 8 x 8 inch square slab. More versatile than large towers, it can be laid down flat (perhaps pushed under a monitor stand) or be stood up vertically. You can also VESA mount it, even attaching it to the underside of your desk to save up more space and keep your PC off the floor. In addition to all of the usual ports and the increasingly common USB-C port, you'll also find a headphone jack, meaning you won't want your tiny desktop too far away if you want to use that. Next, consider that this small desktop is made to survive, to quote Lenovo, "it will run in extreme conditions from the Arctic wilderness to desert dust storms." So, it will probably serve as a data entry point for your dusty lab.
