Yesterday AMD launched its Radeon R9 285 graphics card, and after waiting a day we’re bringing you a roundup of all the R9 285 cards that we’ve spotted.
The Radeon R9 285 AMD's first graphics card based on the Tonga GPU. Actually, that’s not even entirely accurate, as AMD simply hasn’t provided a reference design for the card, leaving it to the AIB partners to sketch up their own boards. Of course, there are reference specifications: The GPU carries 1792 stream processors, with 112 TMUs and 32 ROPs. The reference frequency for the cards is set at up to 918 MHz, with memory running at an effective speed of 5.5 GHz. On most cards, the memory consists of 2 GB of GDDR5 memory, and it always runs over a 256-bit memory interface. This might make it appear slower than the R9 280 that it succeeds, but our review showed that that isn’t entirely the case, and it does this with a TDP that is 60 W lower than the R9 280.
Unsurprisingly, most of the vendors' cards are quite similar to one another. Naturally, they all carry the same GPU, and they all carry the same amount of memory. At this time we haven’t spotted any 4 GB cards just yet. Each vendor has used its own PCB design and cooling solution. While the cooler will affect performance, some of the vendors have also overclocked their R9 285 card a bit, giving them a slight edge in performance.
| Header Cell - Column 0 | GPU Frequency | GDDR5 | Memory Frequency | Cooler |
|---|---|---|---|---|
| Asus R9 285 Strix | 945 MHz | 2 GB | 5.5 GHz | DirectCU II |
| Club3D R9 285 royalQueen | 945 MHz | 2 GB | 5.5 GHz | CoolStream |
| Gigabyte R9 285 WindForce OC | 950 MHz | 2 GB | 5.6 GHz | WindForce 2X |
| HIS R9 285 IceQ X2 | 918 MHz | 2 GB | 5.5 GHz | IceQ X2 |
| HIS R9 285 IceQ X2 OC | 928 MHz | 2 GB | 5.5 GHz | IceQ X2 |
| MSI R9 285 Gaming OC | 973 MHz | 2 GB | 5.5 GHz | TwinFrozr IV |
| Sapphire R9 285 Dual-X OC | 965 MHz | 2 GB | 5.6 GHz | Dual-X |
| Sapphire R9 285 ITX Compact OC | 928 MHz | 2 GB | 5.5 GHz | Row 7 - Cell 4 |
| VisionTek R9 285 | 945 MHz | 2 GB | 5.5 GHz | Row 8 - Cell 4 |
| XFX R9 285 DD | 918 MHz | 2 GB | 5.5 GHz | Double Dissipation |
As far as specifications go, we're going to have to give the crown to MSI with the R9 285 Gaming OC card, as this unit has a core frequency of up to 973 MHz, which is higher than any other card we found. Of course, some buyers may have other preferences, and prefer a smaller card or a more silent card, but as far as performance goes the MSI card will likely sit up top.
Most of the vendors priced their cards at $249, although some premium cards might cost a little more. Hopefully in the future we'll start seeing 4 GB variants come to shelves, as some games do run into memory issues when running on higher resolutions.
