AMD Unveils New Family of GPUs: Radeon R5, R7, R9 With BF 4 Preorder Bundle

MojoKid writes "AMD has just announced a full suite of new GPUs based on its Graphics Core Next (GCN) architecture. The Radeon R5, R7, and R9 families are the new product lines aimed at mainstream, performance, and high-end gaming, respectively. Specs on the new cards are still limited, but we know that the highest-end R9 290X is a six-billion transistor GPU with more than 300GB/s of memory bandwidth and prominent support for 4K gaming. The R5 series will start at $89, with 1GB of RAM. The R7 260X will hit $139 with 2GB of RAM, the R9 270X and 280X appear to replace the current Radeon 7950 and 7970 with price points at $199 and $299, and 2GB/3GB of RAM, and then the R9 290X, at an unannounced price point and 4GB of RAM. AMD is also offering a limited preorder pack, that offers Battlefield 4 license combined with the graphics cards, which should go on sale in the very near future. Finally, AMD is also debuting a new positional and 3D spatial audio engine in conjunction with GenAudio dubbed 'AstoundSound,' but they're only making it available on the R9 290X, R9 280X, and the R9 270X."

Mantle API

[LordMyren]

Personally I would've gone for a mention of Mantle, the proprietary API they are introducing that sidesteps OpenGL and DirectX. I don't really know what it does yet, haven't found good coverage, but DICE's Battlefield 4 is mentioned as using it, and the description I've read said it enabled a faster rate of calling Draw calls.

Using OpenGL or DirectX to 'program' a modern GPU is like using Fortran to program the CPU

Are you saying that OpenGL and DirectX are the fastest? Because Fortran code sure is.

Re:Schlameel, Schlamazel

[SJHillman]

The same thing that happened to the Intel i2, i4 and i6 processors.

So, you're convinced that the slight improvement in performance brought about by a reduction of software overhead is going to completely cripple nVidia? Yeah, sure.

Even if Mantle does produce faster performance (and there's no reason to doubt that it will), the advantages will be relatively small, and about all they might cause nVidia to do is adjust their pricing slightly. The won't be anything that you'll be able to accomplish with Mantle that wasn't possible without it, such is the nature of fully programmable graphics processors.

Game publishers, for their part, will hesitate to ignore the 53% of nVidia owners in favour of the 34% AMD owners. It's highly unlikely that this will cause a repeat of the situation caused by the Radeon 9700, which scooped a big win by essentially having DirectX 9 standardized around it. In that case, ATI managed to capture significant marketshare, but more because nVidia had no competitive products on the market for a year or two after. This time around, both companies have very comparable performance, and minor differences in performance usually just result in price adjustments.

Curious about stability

[PhrostyMcByte]

The idea is that operating systems introduce a huge amount of overhead in the name of security. Being general purpose, they view their primary role as protecting all the other apps from your unstable app. And, lets face it, even AAA games these days are plagued with issues -- I'm really not sure I want games to have low-level access to my system. Going back to the days of Windows 98's frequent bluescreens isn't on my must-have list of features.

John Carmack has been complaining about this for years, saying this puts PCs at such a tremendous disadvantage that consoles were able to run circles around PCs when it came to raw draw calls until eventually they simply brute-forced their way past the problem.

Graphics APIs have largely gone a route that encourages keeping data and processing out of the OS. That's definitely the right call, but there are always things you'll need to touch the CPU for. I'm curious exactly how much of a benefit we'll see in modern games.

Re:Curious about stability

1. today's consoles also run protected mode (or architecture specific equivalent) operating systems too. The userland kernel hardware latencies are present.

2. You're complaining about games? Today's operating systems are hardly any better off. There is no way the vendors can vouch for the security of 10gb worth of libraries and executables in windows 7 or osx. The same is true for OSS. Best practice is to just assume every application and system you're using is compromised or compromisable and mitigate accordingly.

3. IIRC that particular carmack commentary was done to hype up the new gen systems. It's largely bogus. I'm sure the latencies between the intel on-die hd5000 gpu and cpu are lower, but that doesn't mean it's going to perform better overall. Same thing goes with the amd fusion chips used in the new consoles. They're powerful for their size and power draw, but they will not outperform current gaming pc rigs..

Re:without decent drivers

[MojoMagic]

A couple of problems with this statement:
- .Net is not a programming language. Your comparison is just silly.
- In case you meant to refer to C#, no part of this development process is "point-and-click". In this regard, it is no different to C++ (I develop in both).
- It is not interpreted. Nor has it ever been.
- I think you'll find that the simple programs of "a few dozen lines" that you mention would likely be smaller (3 of lines) in C# than C++. But, again, this is a silly comparison and shouldn't be used in any reasonable comparison. If things like this are a problem, you are just using the wrong libraries; in most cases it has little to do with the language directly.

"The difference in performance will be MASSIVE when the rendering features made viable by Mantle are enabled."

I'm sorry but you are full of shit. Memory bandwidth has been the KEY factor in framerates. Not drawcalls. That drawcall bs is propaganda. Transistors > software (provides software developer isn't braindead). Always. The same way CISC was 'slower' then RISC, and the itanium was supposed to be the death of x86 but we still have X86. They found ways around it and to make it faster. Same deal.
