When was the radeon 4870 released

But theoretical performance isn't reality, and nothing can be done if every instruction is a multiply-add or combination of a multiply-add and a multiply, so while marketing loves to trot out big numbers we quite prefer real-world testing with games people will actually play on this hardware.

But before we get to performance, and as usual, we will want to take as deep a look into this architecture as possible. This won't work long term, however. As we push toward moving compute intensive applications to the GPU, developers will not just want -- they will need low level architectural information.

It is impossible to properly optimize code for an architecture when you don't know exact details about timing, latency, cache sizes, register files, resource sharing, and the like. The GPU clock speed improvement is simply due to better cooling as the ships with a two-slot cooler. For general inquiries, please use our contact form.

Therefore it was no surprise to me that a few days after reviewing that product Outlook made that wicked yet sometimes irksome 'ploink' noise with an email from AMD - 'Hey Hilbert, we have a 1GB version of the Radeon HD , check it out please'. Actually it's pretty clever when you think of it. The series really diggs that GDDR5 memory bandwidth, and what's the cheapest thing to do to gain some extra performance?

Increase the framebuffer volume. Now that by itself is not going to work miracles, yet in memory limited situations loads of high quality textures, filtering and AA modes it will help you here and there. Better competition does nothing but benefit the consumer, and we love to see it. All we care about is what performs best in a price class, because that is what benefits our readers. Of course, the core might also have been anticipating the eventual availability of the Radeon 1GB.

In which case, the core falls short. Well, it isn't just that the GTX falls a little short. The fact is that the extra RAM really does make a significant difference in many high quality high resolution situations when playing current games. We didn't expect the gains we see here, and combined with the original stellar performance of the Radeon HD , we have to say that we are impressed.
