AMD Radeon HD 7770 and 7750 GPU Reviews
By now you should all know the drill. A big GPU manufacturer releases a new high-end GPU, based on a new or updated architecture. Then over the course of the next few months, the company continually fleshes out its product stack until a top-to-bottom line-up of new graphics cards emerges, at a wide range of price points, all based on the same architecture.
If you’ve been paying attention as of late, you’ve probably noticed that AMD recently released a couple of high-end graphics cards—the Radeon HD 7970 and 7950—based on the GPU codenamed “Tahiti”, which sports an entirely new architecture, dubbed Graphics Core Next, or GCN. With the launch of the Radeon HD 7900 series set forth, what we have on tap for you today should come as no surprise. AMD’s current high-end products are based on a new architecture, so it’s time to flesh out the rest of the product stack with some new stuff, of course.
AMD is launching two more Radeon HD 7000 series products today, the Radeon HD 7770 and 7750, but unlike the 7970 and 7950, these two new cards are based on a fresh GPU codenamed “Cape Verde”. Cape Verde has essentially the same feature set as the more powerful Tahiti, but is pared down to target a totally different market segment, and be more affordable and power friendly too.
The main features and specifications of the new Radeon HD 7770 and Radeon HD 7750 being released today are outlined in the chart above. We’ll dive into the specifications and take a close look at each card on the next page, but for now the Typical Board Power spec provides a large enough hint to figure out that these cards do not target performance enthusiasts.
With typical board powers of 55 watts (Radeon HD 7750) and 80 watts (Radeon HD 7770), or approximately 4x to 5x lower than the Radeon HD 7900 series cards, it should be clear that these first two members of the Radeon HD 7700 series are targeted at mainstream users or casual gamers looking to upgrade from integrated graphics or an older, previous-generation entry-level graphics card.
The Cape Verde GPU powering the Radeon HD 7770 and 7750 cards, however, is fairly potent given its position in the Radeon HD 7000 series. It does not target the “sweet” spot of the market though; the GPU codenamed Pitcairn, which will power the Radeon HD 7800 series has that distinction. But if you’ve got the need for an affordable graphics card, with a bleeding edge feature set, and just enough oomph for some casual gaming, read on and check out the Radeon HD 7700s.
