Seeing Double

The latest generation of graphics cards from both ATI and NVIDIA is upon us. This is inevitably a signal to both gamers and developers that the bar has been raised. The entry level of these new cards will almost certainly surpass many of the lower mid-range cards, demoting the older cards to the bargains galore. This is good news for both manufacturers and consumers alike; the publicity will attract new customers and upgraders while price conscious buyers can look forward to some good buys. The Radeon X550 is a prime example of a lower range graphics card that is heading for the bargain basement.

Despite using a relatively new 0.11-micron core, it pales in comparison with the next generation Radeon X1300 PRO that we have recently previewed. That is not to say that the Radeon X550 is obsolete technology though. Far from it, the performance of this card still holds its own for most games if you are not that fussy about sacrificing some eye candy for better frame rates. Besides, some vendors have their own ideas on how to revive a GPU – overclocking. Given these circumstances, it is appropriate that today, we have an enhanced, overclocked Radeon X550, the Palit Radeon X550V+ 256MB.

A compact package from Palit for its Radeon X550V+ 256MB.

It was not too long ago that we reviewed a Radeon X550. Equipped with 256MB of DDR2 memory chips and based on the same R370 core, the GeCube Radeon X550 that was reviewed, came overclocked too and gave solid results that easily bettered the reference card. Taiwanese vendor Palit, one of ATI's official AIB partners (and the company behind the XpertVision brandname) has a comparable offering today. In fact, from the size of the frame buffer to the pre-overclocking of the core and memory, the similarities between the two are aplenty. The Palit Radeon X550V+ 256MB has an overclocked core with the same frequency (450MHz) as the GeCube. The 2.8ns rated DDR2 Infineon memory chips on the Palit Radeon X550V+ are overclocked to 756MHz DDR, a respectable leap from the reference frequency of 500MHz DDR. This is also mimicked on the GeCube, but the frequency is 750MHz for that card. Here then is the rest of the technical specifications for the Palit Radeon X550V+ 256MB:
