![]() ![]() AMD bakes GPUs on the all new 28nm node, in very simple wording the smaller the die size the more more transistors AMD can put on a smaller area, often at a lower voltage. Yes, we start off with the GPU overview (we'll discuss architecture later). so the R280X is a Tahiti / R7970 GHz then ? That is the kind of flexibility we like a lot alright. So if you have three of the same monitors you could hook up one towards HDMI, once to DVI and once to DP. You can now mix and match any monitor (similar monitors) output and create an Eyefinity setup. Very clever.Įyefinity also has received a small update. So if you setup Eyefinity with three screens the six speakers in your monitors will now be configured as front left/mid/right channels. Interesting is that AMD now implemented next generation digital multipoint audio with smart channel splitting. With the launch of the R7 and R9 series you will also see Eyefinity updated towards version 2.0 DDM, audio is now fully supported (you hear audio on the actual monitor it's played off), the 5x1 landscape mode is introduced, and you may now create custom multi-monitor resolutions. We'll address all the features separately of course. The GPU architecture has remained the same though comparable towards the last-generation products, AMD still uses the 28nm process technology, the cards are PCIe gen 3 compatible and there have been significant changes on power consumption. AMS always has been much more reserved with the difference inbewteen baseline and maximum frequency, so the difference in values won't be extremely big. In return the card will adaptive manage fan control, clock frequency and voltages (dynamic). The GPU clock will get a baseline and maximum frequency, in-between these two values the card will clock up/down based on power draw/limiters, performance and heat. This means that there no longer is a fixed clock on these cards. And much like NVIDIA does, AMD now fully implemented a 'Turbo' feature much like NVIDIA's boost technology on all of their products. And who can remember Oland, that mobile GPU ? Well peek at the R7 250 specs, looks familiar right ? There are a number of changes though to be found in clock and memory frequencies so overall there will be slight performance increment's. The R7 260X is a new GPU, but the R9 270X and R9-280X both are derivatives of the Pitcairn and Tahiti GPUs respectively. Yes, much like NVIDIA has done with the 700 series AMD is doing something very similar. R9 280X (previously the R7970 Ghz / Tahiti) R9 270X (previously the R7870 Ghz / Pitcairn) API - DirectX 11.2 / OpenGl 4.3 / Mantle.The entire segment from top to bottom has been released in Q1 2012, but most of the 2013 models are respins, the exception being the R7-260X and the R9-290/290X graphics cards. Enthusiast level Hawaii = R9-290 and 290X.High-end level = Tahiti = Radeon HD 7900 series / R9 series.Mainstream level = Pitcairn = Radeon HD 7800 series / R7 series.Entry level = Cape Verde = Radeon HD 7700 series / R5 series.Pitcairn would be the codename the mainstream products (7800) will hide under, and Tahiti is the codename for the GPUs used on AMD's most high-end graphics cards. When you notice 'Cape Verde' that's entry level, the 7700 series that was just released. It's simple really, in the market we have entry level, mainstream and high-end products. Over the past two years you have been hearing about several codenames and that can be a little confusing. ![]() ![]() So let's deal with a quick overview of the AMD new product range first. ![]()
