Today we are going to bring you the review of the Sapphire ATI Radeon HD 5750 , So lets check the review






Core Clock: 700MHz

Memory Clock: 1.15GHz (4.6GHz effective)
Memory: 1GB GDDR5

Major hardware releases can be a little befuddling for a tech journalist, as there’s a whole load of new numbers to learn. While this is very much par for the course, ATI’s new Radeon HD 5000-series of cards are a particular headache for me. There are just too many fives, sevens and eights. The last of ATI’s launches we’re looking at is the low end Radeon HD 5750, a cut-down version of the HD 5770, which itself is a cut-down version of the Radeon HD 5870 and HD 5850. See what I mean?


Like the HD 5770, the HD 5750 is based on ATI’s Juniper GPU, comprising effectively half of the Cypress GPU of the HD 5800 cards. The HD 5750 flavour of Juniper has nine cores, meaning there are 720 stream processors and is clocked at 700MHz, with the faster HD 5770 equipped with ten cores (800 stream processors) and clocked twenty percent higher at 850MHz.

HD 5750 cards are available in either 512MB or 1GB flavours, Later has 1GB of GDDR5 clocked with a stock rated frequency of 1.15GHz (4.6GHz). Like the HD 5770, the HD 5750 has a 128-bit memory interface, meaning that this card has 73.6GB/sec of memory bandwidth.

Technology and Batmobile Cooler

Fabricated on TSMC’s new 40nm technology, the chip uses less power and generates less heat than previous GPUs. ATI has eschewed the Batmobile cooler of the rest of the HD 5000-series for the HD 5750 in favour of a simple aluminium heatsink and fan. However, Sapphire has ditched the stock ATI cooler in favour of its own aluminium heatsink-plus-fan cooler. It looks a bit better than ATI’s, as the fan and heatsink are both larger, and the fan blows directly down on to the heatsink, rather than being embedded in it. The cooler looks neat, but throws hot air in all directions and not out of the rear of your case as the coolers of the other HD 5000-series cards do.


The card has two DVI outputs, plus HDMI and DisplayPort; as with the HD 5800 cards, you can use three of these outputs concurrently.

In the Box

In the box you’ll find the usual gubbins such as a driver disc, a Molex-to-PCI-E power adaptor (for the single 6-pin PCI-E power input) and a DVI-to-D-Sub adaptor. More exciting is the pre-order Steam key for Colin McRae Dirt 2 which will be one of the first DirectX 11 games when it hits shelves in December, so it could potentially show off some of the features in Microsoft’s new graphics API. However, the game will have to be relatively undemanding if the entry-level HD 5750 is to have a chance of running it in its full DX11 splendour.

The Sapphire Radeon HD 5750 1GB comes complete with a two-year warranty that includes cover for parts and labour. During the first year of the product’s life, your point of contact should be the retailer. However, if you’re having problems getting hold of the retailer (or the retailer goes out of business), you should contact Sapphire’s support team directly. During the second year of the warranty period, you should talk directly with Sapphire. This is pretty much in line with what other ATI board partners offer, and while the two year warranty is more than you’re legally entitled too, it isn’t as comprehensive or as long lasting as what’s available from some of Nvidia’s board partners.


Overclocking with ATI’s new 40nm GPUs is a more fruitful process than with previous-generation chips. Using AMD’s GPU Clock Tool, we managed to bump the Sapphire’s GPU from 700MHz to 840MHz, and the memory from 1.15GHz to 1.34GHz (5.36GHz effective). In Crysis, this overclock yielded an extra 3fps across the board, meaning that the budget card performed almost identically to its more expensive brother. Sadly, Folding@home doesn’t yet work on the new HD 5000-series GPUs, so Nvidia is currently still the way to earn bragging rights.

It should come as no surprise that the HD 5750 sucked the least amount of power from the wall during our tests: our PC consumed 132W when idle and 192W when under load. The Sapphire cooler not only kept things cool, but also whisper-quiet, keeping the GPU at just 26?C above room temperature when under load with a practically inaudible purr.

We’re at the crossover stage of DirectX 10 to DirectX 11 graphics cards, so the price of the older-generation GPUs like the GTX 260-216 is being driven down by the newcomers like the ATI HD 5770 and HD 5750. For this reason, new budget graphics cards often struggle to hold their own against old mid-range cards, and that’s exactly what has happened with the HD 5750. While Sapphire has made a good fist of it, with a Dirt 2 pre-order code in the box and a cool and quiet third party cooler, the HD 5750 is disappointing when it comes frame rates.

You may be swayed by the lure of DX11 support and convinced that buying a HD 5750 over a GeForce GTX 260 (rev 2) would be more future-proof but considering that the HD 5750 struggles to run some games smoothly now, we couldn’t disagree with this more; when looking at a graphics card, you should always look at the performance first and the features second.

This is especially true for new versions of DirectX, as it will be a year or two before DX11 games are ubiquitous and even longer until DX11 becomes a mandatory feature, by which time this card will be well past its sell by date. If you need an upgrade with this sort of budget, a GTX 260 (rev 2) is by far the best option for just £10 more, while anyone owning a decent DX10 mid-range card like last years HD 4850 or HD 4870 should sit tight or find enough extra cash for the the HD 5850, which offers a lot more performance to go with its DX11 features.
