Today, let’s take a look at the new Radeon HD 7750, a USD 110 video card based on the latest graphics architecture from AMD, dubbed “Graphics Core Next” or simply “GCN,” which supports the new PCI Express 3.0 connection and the latest DirectX version (11.1).
For a detailed explanation of the new features present on this latest architecture, please read our Radeon HD 7970 review.
The Radeon HD 7750 and Radeon HD 7770 use the codename “Cape Verde.” By the way, this country is located in the Northern Hemisphere, not in the Southern. (This new GPU architecture from AMD used by these video cards is codenamed “Southern Islands.”) We’ve already reviewed the Radeon HD 7770.
At USD 110, the new Radeon HD 7750 competes with the GeForce GTS 450 and is a little cheaper than the GeForce GTX 550 Ti. In the table below, we compare the main specifications of the video cards included in our review. The prices listed below do not include rebates and are for the models with the clock and memory configurations listed below. Prices were researched at Newegg.com on the day we published this review, except for the Radeon HD 7750 and the Radeon HD 7770, which are the prices advertised by AMD.
|Video Card||Core Clock||Shader Clock||Memory Clock (Effective)||Memory Interface||Memory Transfer Rate||Memory||Shaders||DirectX||Price|
|Radeon HD 7750||800 MHz||800 MHz||4.5 GHz||128-bit||72 GB/s||1 GB GDDR5||512||11.1||USD 110|
|Radeon HD 7770||1 GHz||1 GHz||4.5 GHz||128-bit||72 GB/s||1 GB GDDR5||640||11.1||USD 160|
|GeForce GTS 450||783 MHz||1,566 MHz||3.6 GHz||128-bit||57.7 GB/s||1 GB GDDR5||192||11||USD 110 – USD 140|
|GeForce GTX 550 Ti||900 MHz||1.8 GHz||4.1 GHz||192-bit||98.4 GB/s||1 GB GDDR5||192||11||USD 120 – 130|
Today, only the LGA2011 Core i7 processors (“Sandy Bridge-E”) have a PCI Express 3.0 controller. In our Radeon HD 7970 review, we discovered that, at this time, there is no difference between using a PCI Express 2.0 or a PCI Express 3.0 connection. Since the reviewed video card is a mainstream product, we decided to use a different testing platform, based on a Core i5-2500K processor.
Now let’s take a complete look at the AMD Radeon HD 7750 reference model.
