Radeon X550 low-cost graphics card

Radeon X550 low-cost graphics card

 

Review If you aren't a gamer, integrated graphics may seem the best imaging option to choose for your next PC. Integrated graphics engines may be cheaper than add-in cards, but they can hit system memory performance hard, and since on-board graphics are usually only available on budget chipsets and motherboards, you may also miss out on key features such as RAID storage or dual-monitor support, writes Andrew Miller.
A better option is to buy a cheap discreet graphics card, and at £52, you'll struggle to find one much cheaper than the Sapphire X550.
The X550 sounds like it should be an entirely new product range, but is incredibly similar to the X300. The X300 is built using a 110nm fabrication process and is incredibly small, kicking out very little heat. But with only four pixel pipelines and two vertex pipelines, it hardly sets itself up as a gamer's dream.
The X300 has a 325MHz core and a 200MHz (400MHz effective) memory speed. Not all X300s are the same, however. Some employ HyperMemory technology, which uses system memory to supplement the frame buffer. Most cards have a 128-bit memory bandwidth, but not all.
The X550 is essentially a speed-bumped X300. This one, from Sapphire, has 256MB of memory with 128-bit memory bandwidth. It runs with a 400MHz core and 250MHz (500MHz effective) memory.
Abit recently launched the X300SE, which uses 128-bit memory and is guaranteed to overclock to 405MHz on the core and 255MHz (510MHz effective) for the memory - higher, in fact, than the X550. Not only this but, at £37, it's cheaper. We decided to use this for comparison, to see if it was worth spending the extra £15.

AMD Radeon HD 7970: 28nm Tahiti GPU Review

We have been hearing about AMD’s “Southern Island” family of graphics processors for quite some time. Even during briefings for the Northern Island series of products which ultimately became the Radeon HD 6000 series, news about Southern Islands was already trickling out. Rumors about these parts have been rampant for what seems like ages, but now, just in time to get all you hardcore gamers fired up this holiday season, AMD is officially taking the wraps of Southern Islands. More specifically, today AMD is announcing their latest flagship single-GPU, the Radeon HD 7970. As you may suspect, if you paid attention to Eric Demer’s excellent keynote address at the AMD Fusion Developer Summit and the resulting onslaught of news that followed, the top-of-the-line GPU in the Southern Islands family—codenamed Tahiti—features AMD’s totally new Graphics Core Next (GCN) architecture. In addition to being the first GPU to feature GCN, Tahiti is also AMD’s first GPU to be manufactured at 28nm, their first with PCI Express 3.0 connectivity, the first with DirectX 11.1 support, and the first to sport a few other new technologies we’ll cover a little later (ZeroCore, PRT, multi-point audio). There’s a lot to cover, so we’re not going to take up any more bandwidth telling the backstory. Up next are some preliminary details regarding the Radeon HD 7970 and other GPUs in the Southern Islands family, followed by a deep dive into the technology and a full performance profile of the fastest single-GPU money can (almost) buy...

We’re going to go into much more detail a little later, but here are some preliminary details regarding the Tahiti-based Radeon HD 7970. The GPU is outfitted with 2,048 stream processors featuring AMD’s Graphics Core Next architecture and is paired to 3GB of GDDR5 memory connected over a 384-bit wide memory bus. The maximum number of displays supported per GPU is six, just like the previous generation Radeons, but the display output configuration has changed; one of the DVI outputs has been nixed.

 

The Tahiti GPU isn’t the only memory of the Southern Islands family slated for release, however. It is the only one to feature GCN, but new mainstream and “sweet spot” 28nm GPUs are coming too. The Pitcairn core will power the Radeon HD 7800 series, while Cape Verde will be the foundation of the Radeon HD 7700 series. We’ll have more details regarding those parts in the coming months. Before we move on to the inner working of Tahiti and the Radeon HD 7970 in general, we should highlight a few previous HotHardware articles that are pertinent to today’s announcement. Although it’s based on a new GPU, the Radeon HD 7970 shares many features with previous-generation Radeons, like CrossFire, Eyefinity, PowerTune, UVD, and more. Since we won’t be covering those topics in depth here again, we’d suggest giving the following articles a glance.

NVIDA GeForce GTX 560 Ti with 448 Cores

NVIDA GeForce GTX 560 Ti with 448 Cores

 The GeForce GTX 560 Ti with 448 cores has—you guessed it—448 CUDA cores arranged in 14 SMs, with 56 texture units and 40 ROPs. The reference specifications call for a 732MHz core clock with 1464MHz CUDA cores. 1.2GB of GDDR5 memory is linked to the GPU via a 320-bit bus and the memory is clocked at an effective 3800MHz data rate. The cards will require a pair of 6-pin PCI Express power leads and support up to 3-way SLI.

As is the case with most NVIDIA GPU releases, however, the GeForce GTX 560 Ti with 448 cores will be offered in overclocked editions by some of NVIDIA’s board partners. The Zotac GeForce GTX 560 Ti 448-Core Limited Edition card you see pictured here is an overclocked variant. 

The Zotac GeForce GTX 560 Ti 448-Core Limited Edition strays from NVIDIA’s reference design in that is sports a custom, single-fan cooler and overclocked GPU. The GPU clock is increased to 765MHz with 1530MHz CUDA cores, but the memory clock remains unchanged from the 3800MHz (effective data rate) of the reference design.

As you can see in the pictures above, the card is two-slots wide and features dual DVI outputs along with one HDMI output and one DisplayPort output.

DDR2 vs DDR3: which RAM should you buy?

DDR2 vs DDR3
But just what are the pros and cons of DDR2 and DDR3? Is it desirable or even possible to upgrade from the former to the latter? The first thing to appreciate is that the two memory types are completely incompatible with each other. Everything from voltages to timings and signalling is different.
Fortunately, they're physically incompatible, too. A repositioning of the slotted groove on DDR3 sticks and sockets means you can't accidentally insert the wrong memory into you motherboard. Of course, a change of physical form factor also means the minimum requirement for changing memory types is a new motherboard.
However, you may need a new CPU, too. Some Intel CPUs for the LGA775 processor socket from the Core 2 era are compatible with both DDR2 and DDR3. Likewise AMD processors for the AM3 socket are DDR3 compliant and some will also drop into older AM2 boards and work happily with DDR2 memory. To find out whether you can hold onto your processor, check the product information at www.amd.com and www.intel.com.

New Radeon HD 6930 set to crush sub-$200 market.

New Radeon HD 6930 set to crush sub-$200 market.

As if in response to Nvidia's latest offering (th

e limited edition GTX 560 Ti), AMD is reportedly prepared to release the HD 6930 just in time for last-minute Christmas shoppers. The HD 6930 falls just short of the HD 6950, and at the rumored $180 pricepoint may provide new competition for the HD 6870. It's curious why AMD would release a new card to compete with

their existing product in the same price range, though it's likely Nvidia's recent release was the impetus.

For those who appreciate having options (or Eyefinity), this reference card is expected to offer one HDMI, two DVI, and two mini DisplayPort outputs. Although the overall specs of this card are reduced from the HD 6950, it supposedly has an increased maximum power consumption of 225W, up from 200W on the HD 6950

The new GeForce GTX 560 Ti 448 cards are at Newegg.

Our Newegg parser (the thing the puts the price next to card) is not working so I had to craft these links by hand. If you want to help support this site by buying one of these new cards, please use the links below:

AMD vs Nvidia: The DX11 era

AMD vs Nvidia: The DX11 era
Of course, graphics technology waits for no man and much has changed since the Radeon HD 4000 series and GeForce GTX 200 hit the market in 2008. Late last year AMD unleashed the Radeon HD 5000 series, the world's first family of graphics chips with support for the latest DirectX 11 multimedia API from Microsoft, as seen in Windows 7 but also av

ailable as an update for Windows Vista.

It took a little longer for Nvidia to respond in kind with the GeForce GTX 400 family. It eventually turned up earlier this year and since then its been these two pixel pumping graphics architectures fighting it out for top DX11 honours.

Topping the current single-GPU tables, therefore, are the ATI Radeon HD 5870 and Nvidia Geforce GTX 480. Thanks to AMD's greater emphasis on value, the GTX 480 weighs in around £100 more expensive at £430 or so.

For the money Nvidia gives you an extra billion transistors for a faintly ridiculous total of three billion. You also get a little more memory as standard, 1.5GB to the 5870's 1GB. However, it's worth noting that 2GB variants of the 5870 are now available for less than the 1.5GB GTX 480.

Anyway, what you don't get from the 480 is a huge performance advantage. Yes it's a little quicker than the 5870. But not nearly as much as it needs to be given the extra cost and complexity.
