The ‘enthusiast' range (high mid-range or low high-end, depending on how you want to look at it), flagship segment when it comes to graphics cards, counts for a high volume of sales. Naturally, then, we were excited to get our hands on the Radeon HD 7800s to see where this series stands in comparison to the old generation of AMD cards, but also in comparison to the costly Radeon HD 7900s. One thing is already clear, the Radeon HD 7870 (expected to cost around £300) will have plenty under the bonnet to cope with the latest games. The generic models sent to the press look exactly like the Radeon HD 7970 and Radeon HD 7950. The Radeon HD 7870 is nevertheless 2.5 cm shorter than the 7970, making it 'just’ 25 cm long. A radial fan (or blower) is still used in the cooler. This has the advantage of sending the hot air straight out of the casing, unlike models with an axial fan such as the Radeon HD 7770 for example. The fan nevertheless proved slightly disappointing as it makes quite a whirring noise, even at idle, though we should say that in a standard casing it shouldn’t be louder than your other components. In a casing designed to be quiet however, it could be a little more annoying. Once you’ve fired up a video game, the whirring is kept at an acceptable level and shouldn’t be too disturbing.
At long last the line up is complete, with the AMD Radeon HD 7870 and AMD Radeon HD 7850 finishing things off for AMD's next generation graphics family.Yes, we've seen the (almost) very top-end of AMD's graphics stack, with the AMD Radeon HD 7970 and Radeon HD 7950, and recently we've seen the bottom end of its Graphics Core Next (GCN), 28nm Southern Islands set with the AMD Radeon HD 7770 and Radeon HD 7750.Why do we say almost the very top-end? Well, so long as AMD stays true to form we should expect to see a dual-GPU card based on the Tahiti GPU of the HD 7900 series cards before too long. That AMD Radeon HD 7990 (it's not much of a stretch to think it'll follow the naming conventions of the AMD Radeon HD 6990) will represent the pinnacle of AMD graphics.And is likely to be sitting somewhere in the region of £600-£700. Eek.But that ridiculous end of the graphics market is not what we're looking at with the AMD Radeon HD 7800. This here represents the start of its enthusiast range of cards; serious gaming starts here, according to AMD.These are, according to AMD, the cards for gamers wanting to hit the highest graphics settings in-game without having to spend £300 on a GPU.
As we've mentioned, the Pitcairn GPU powering the Radeon HD 7800 series cards is based on the Graphics Core Next (GCN) architecture and has essentially the same feature set as its higher-end counterpart (Tahiti) found on the Radeon HD 7900 series. Like Tahiti and the mainstream Cape Verde GPUs, Pitcairn is manufactured using TSMC's advanced 28nm process node. The Pitcairn GPU, however, is comprised of roughly 2.8B transistors and outfitted with a maximum of 1,280 stream processors (to Tahiti's 2,048) arranged in 20 compute units with 64 stream processors each. Pitcairn also sports dual Geometry engines, 32 ROPs, 80 texture units, and a 256-bit GDDR5 memory interface; double-up on Cape Verde and you've basically got Pitcairn. According to AMD, the die size of the chip is a relatively small 212 square millimeters (Tahiti is 365mm2, Cape Verde is 123mm2). Although the Pitcairn GPU powering the Radeon HD 7800 series is pared down somewhat to hit more affordable price points, it doesn't skimp on any features. With fewer stream processors, ROPs, and texture units, and a narrower memory interface, Pitcairn's performance will be lower than Tahiti, but its feature set remains unchanged.
AMD has been heating up the winter video card market with its release of cards in its new 7000 series (code-named "Southern Islands"), first with the release of the highest-end models (the Radeon HD 7970 and 7950) and later the more mainstream options (the Radeon HD 7770 GHz Edition and 7750). So it only makes sense that the company would continue (and perhaps end?) the season by filling in the gap between the two lines. Hence the AMD Radeon HD 7870 GHz Edition, which is priced (at $349 list) and powered to provide a strong and sensible entry point into the enthusiast gaming graphics realm. At that, the 7870 definitely succeeds, and those looking for a sub-$400 current-generation solution won't presently find a better card, but there are better values (peddling not vastly inferior performance) to be had. You do, of course, get the full swath of technologies that AMD has been smartly using to build out the 7000 series. These begin with the 28nm Graphics Core Next architecture, which improves utilization, throughput, and multitasking by giving each compute unit the ability to execute instructions from multiple kernels at once.
AMD's latest generation GPU series is really starting to take shape now. Having been blown away by the performance of the Radeon HD 7900 series and then let down by the steep pricing of the HD 7700 series, we are keen to see what AMD has to offer with the new HD 7800 series. Today marks the release of the 'Pitcairn' GPUs (code-name) which make up the the Radeon HD 7800 series. As you would expect the series consists of two GPUs: the Radeon HD 7870 and Radeon HD 7850, designed to occupy the ample $200 to $400 range. Like its higher and lower-end siblings, the new HD 7800 series is built using the 28nm design process and is also based on AMD's Graphics Core Next architecture. Back in January, the 'Tahiti' GPUs, better known as the Radeon HD 7900 series, was released to become the fastest single GPU on the market. At the top of the food chain, the Radeon HD 7970 and HD 7950 are exceptionally fast GPUs and with a retail price of $549 and $449, respectively, AMD is making sure gamers pay top dollar for those high frame rates. Next up we were faced with the Radeon HD 7700 series which went by the codename 'Cape Verde'.
