     AMD Catalyst 11.4

    Although we’re already at the end of the month, AMD has only just published the April version of its Catalyst drivers. On the menu, several innovations in the control panel, with, little by little, traces of the old version disappearing. AMD has just added two assistants to facilitate detection of multiple screens and set-up Eyefinity groups.

    AMD has also added an automatic update search feature. On by default, it can be deactivated and carries out the search every fifteen days.

    In terms of performance in games, AMD says that there’s a series of significant gains on the Radeon HD 6800s/6900s when anisotropic and antialiasing is on:
    - Up to 15% in Call Of Duty Black ops in mono GPU
    - Up to 15% in Battleforge in mono/multi GPU
    - Up to 20% in Batman Arkham Asylum in mono/multi GPU
    - Up to 8% in Alien vs. Predator in mono/multi GPU

    Other gains have been announced in mono/multi GPU in Civilization 5 (15%), Far Cry 2 (6%), Just Cause 2 (9%) and Lost Planet 2 (10%). In case you were wondering, the Crossfire driver for Crysis 2 still hasn’t been corrected however. We’ll get it one day… maybe…

     OCZ Vertex 3 Max IOPS

    OCZ has launched a new version of its Vertex 3, the Vertex 3 Max IOPS. Using 3xnm MLC NAND, compared to 25nm MLC NAND, this version has been specifically designed to give the best possible performance with random 4 KB accesses. More than the engraving, it’s the choice of chips using 4 KB pages, and not the 8 KB pages used on high capacity 25nm engravings, which will make the difference.

    550 MB/s reads and 500 MB/s writes have been announced for compressible data and 500-510 MB/s (reads) and 230-240 MB/s (writes) with incompressible data. With incompressible data, we measured the Vertex 3 120 and 240 GB SSDs at 163 MB/s and 279 MB/s respectively, which represents a big gain for the 120 GB version and a slight fall on the 240 GB.

    In terms of IOPS, we got 35,000 and 55,000 reads on the 120 GB and 240 GB MAX IOPS versions respectively, compared to 20,000 and 40,000 on the standard versions. Writes are up from 60,000/60,000 to 75,000/65,000.

    These very high numbers should however be put into context as they were achieved with very compressible data and 32 simultaneous commands. OCZ is showing willing and has also given the scores obtained in AS-SSD with incompressible data and a single command. You then get 14 and 19 MB/s with 4K reads (3500 and 4750 IOPS), 60 and 65 MB/s in writes (15,000 and 16,250 IOPS), which are standard scores, even strangely low for the 120 GB version with 4K reads.

    When it comes down to it then, even in intensive usage the difference between the Vertex 3 and Vertex 3 Max IOPS are likely to be inexistant. The Vertex 3 Max IOPS has higher numbers to appeal to benchmark fanatics, as well as 3xnm MLC that is reputed to last longer, but will come in at between €20 and €40 more than the Vertex 3.

    Following the GeForce GTX 460, it’s now the GeForce GTS 450’s turn to be reworked by NVIDIA. As with the other reworked cards in the GeForce 500 range, the resultant GeForce GTX 550 Ti enjoys higher clocks and higher performance. Does this mean NVIDIA now have a more competitive model to face down the Radeon mid-range? We’re going to try and answer this by giving our analysis of the DirectCU TOP model from Asus.

    Crucial has just put a new firmware online for its C300 SSD range. According to Crucial this new version improves the reliability of the C300 and eliminates the lags experienced by some users.

    The update doesn’t scrub your data but, as always with any storage device update, it is advisable to back up first.
