The picture of the MSI card above was thieved from the company’s website, and it’s actually of its R9 270X Twin Frozr IV. That’s something that our results will prove won’t matter much, or at all, for most people. The R9 280 has 3GB of GDDR5 on tap, while the R9 285 has to settle with 2GB. Where the biggest difference lays – not counting the architecture change, of course – is with the total memory. The reference R9 285, by contrast, peaks at 918MHz, while our MSI sample bumps that to 973MHz. For comparison’s sake, the reference R9 280 peaks at 933MHz, whereas Sapphire’s version capped at 950MHz. However, paper specs don’t take into consideration architectural enhancements, so clock-for-clock, the R9 285 could be as fast, or a tad faster, than the R9 280.Īs you’ll see on the results pages, the MSI Radeon R9 285 Twin Frozr IV edition we were supplied with is in fact a bit faster than the R9 280 – at least, against Sapphire’s Dual-X version of the R9 280.
The reason for that was simple: The specs told me to. When I wrote about the R9 285 not long after its announcement, I put it underneath the R9 280 in this table.

To gain a better understanding of exactly where the R9 285 fits into AMD’s current lineup, we can make use of this table: AMD Radeon Series Overall, not a lot here that affects gaming specifically, but great enhancements overall. Some of the other improvements include parallel instruction processing between the SIMD lanes, an improved compute task scheduler, and a pre-scalar that improves high ratio downscaling quality. Another promised boost is with tessellation AMD says that we could expect a 2~4x improvement in throughput, becoming more effective as the tessellation factor is increased. There are also new 16-bit floating-point and integer instructions that emphasize lower power use in compute and media processing, something that can also dramatically improve transcoding performance when compared to the competition. That’s without question a very considerable gain. In a particular example, the R9 285 (256-bit) is shown to peak at just over 40GB/s 5500MHz, while the R9 280 (384-bit) 5000MHz peaks at just under 30GB/s. At the forefront, the memory architecture has been vastly improved, promising up to a 40% boost in bandwidth even with a smaller bus width. Let’s take a moment to explain some of what AMD’s promising with its latest GCN architecture. As NVIDIA’s GTX 800 (or 900, as it’s rumored to be called) series will also be based around Maxwell, it’s easy to understand why AMD would want to give us a taste of what it has to come.

What we had was a ~$150 GPU option that could handle all of today’s games at 1080p resolution and with decent detail levels. The first series to be built around Maxwell was GeForce GTX 750, and to say that I was impressed with it ( the Ti in particular) would be an understatement. To understand why Tonga, and its future derivatives are important, it’s best to look back to NVIDIA’s launch of Maxwell earlier this year. Its core is called “Tonga” (Pro), named after the Kingdom of Tonga, an archipelago in the South Pacific Ocean.
Instead, the R9 285 is the first card to feature the next iteration of AMD’s Graphics Core Next (GCN) architecture. You see, the R9 285 isn’t merely a speed-bumped product, or one that’s painfully tweaked to somehow fit inside the normal lineup just because one needs to be there for the sake of quick headlines. It’s not uncommon for a GPU vendor to release a new card model in advance of a competitor launch, but this time, things are a little different. The result of that ambition comes to us in the form of the Radeon R9 285, a card that the company announced during its “30 Years of Graphics & Gaming” event, held two weeks ago. At this point, it’s no secret that NVIDIA’s next generation GeForce cards are going to be announced soon, and that’s a fact that AMD didn’t want to waste any time capitalizing on.
