AMD Catalyst 15.5 to 15.15 Performance Check - Validating AMD R9 390 Testing

During the course of our review of the new Sapphire Nitro R9 390 8GB card earlier this week, a question came up on driver support. For testing the R9 300-series as well as the Fury X cards, AMD provided a new Catalyst 15.15 beta driver. The problem is that these drivers would not install on the Radeon R9 200-series cards. That's not totally uncommon on new GPU releases but it does seem a bit odd considering the similarities between the R9 390 and the R9 290, for example.

That meant that in our review we had to use the Catalyst 15.5 beta for the Radeon R9 290X and the Radeon R9 290 GPU while using the newer Catalyst 15.15 beta for the Sapphire Nitro R9 390. Eyebrows were raised as you would expect as any performance differences between the new cards and the old cards would have to take into account the driver changes as well. But since we couldn't install the new driver on the old hardware, we were stuck, and published what we had.

Since then, a driver with some INI modifications that allows Catalyst 15.15 to be installed on Radeon R9 290X/290 hardware was built and uploaded from the Guru3D Forums. Today I installed that on our XFX Radeon R9 290 4GB card used in our R9 390 review to re-run a few game tests to see what changes we saw, if any. This would help us address any concerns over the updated driver causing performance changes rather than the hardware changes.

(Note: I realize that using an INI hacked driver isn't exactly going to pass QA with AMD, but I think we are seeing results that are close enough.)

First up, let's look at Grand Theft Auto V.

In GTA V we see that the average frame rate at 2560x1440 goes from 39.5 FPS to 40.5 FPS, an increase of about 2-3%. That's minimal but it is interesting to see how the frame rate consistency changes as we move down the sliding scale; pay attention to the orange and pink lines in the FPS by Percentile graph to see what I am referencing. As you move into the slower frame times in our testing, the gap between the 15.5 and 15.15 driver begins to widen slightly, indicating a little more frame time consistency in 15.15 release.

But what about BF4 or Metro: Last Light?

The new Radeon R9 300-series

The new AMD Radeon R9 and R7 300-series of graphics cards are coming into the world with a rocky start. We have seen rumors and speculation about what GPUs are going to be included, what changes would be made and what prices these would be shipping at for what seems like months, and in truth it has been months. AMD's Radeon R9 290 and R9 290X based on the new Hawaii GPU launched nearly 2 years ago, while the rest of the 200-series lineup was mostly a transition of existing products in the HD 7000-family. The lone exception was the Radeon R9 285, a card based on a mysterious new GPU called Tonga that showed up late to the game to fill a gap in the performance and pricing window for AMD.

AMD's R9 300-series, and the R7 300-series in particular, follows a very similar path. The R9 390 and R9 390X are still based on the Hawaii architecture. Tahiti is finally retired and put to pasture, though Tonga lives on as the Radeon R9 380. Below that you have the Radeon R7 370 and 360, the former based on the aging GCN 1.0 Curacao GPU and the latter based on Bonaire. On the surface its easy to refer to these cards with the dreaded "R-word"...rebrands. And though that seems to be the case there are some interesting performance changes, at least at the high end of this stack, that warrant discussion.

And of course, AMD partners like Sapphire are using this opportunity of familiarity with the GPU and its properties to release newer product stacks. In this case Sapphire is launching the new Nitro brand for a series of cards that it is aimed at what it considers the most common type of gamer: one that is cost conscious and craves performance over everything else.

The result is a stack of GPUs with prices ranging from about $110 up to ~$400 that target the "gamer" group of GPU buyers without the added price tag that some other lines include. Obviously it seems a little crazy to be talking about a line of graphics cards that is built for gamers (aren't they all??) but the emphasis is to build a fast card that is cool and quiet without the additional cost of overly glamorous coolers, LEDs or dip switches.

Today I am taking a look at the new Sapphire Nitro R9 390 8GB card, but before we dive head first into that card and its performance, let's first go over the changes to the R9-level of AMD's product stack.
