In parallel with traditional GPUs, chips built in to mobile devices continue to improve in terms of performance and functionality. Imagination, a major player on the market, has recently announced a new graphics chip: the PowerVR SGX545. This is a successor to the Power VR SGX535 that is used in the Apple iPhone 3GS. For the nostalgic among us, the Dreamcast was also equipped with a PowerVR (a Power VR2, aka CLX2)!
This new version of the chip is based on a programmable architecture that is compatible with DirectX9 and 10.1, OpenGL ES 2.x, OpenGL 3.x, OpenVG 1.x and OpenCL 1.x. With these APIs traditionally found in desktop applications, porting ought to be facilitated to a certain extent. According to Imagination, OpenCL compatability should enable the exploitation of all the power of the chip for usage such as image processing and video, physics in gaming, cryptography and so on.
The SGX545 can process up to 40 million polygons per second with a fillrate of 1 Gpixel per second (at 200 MHz). This is equivalent to a GeForce3 / GeForce 4 type chip, which, in terms of an MID, netbook, smartphone or other low resolution mobile device, is fairly comfortable.
Announced at the same time as the NVIDIA Tegra 2, this chip is already reported to have been licensed by one partner.

Among the multitude of available controllers for SSDs, the Samsung controller is one of the better ones, with an attractive price/performance ratio. The Samsung controller is used notably in the OCZ Summits, the Corsair P series and the Kingston V+s.
Although the first two had already published firmware with TRIM compatibility, Samsung was not yet up to speed. Owners of the PB22-J could flash with the Corsair firmware (the two drives being identical) but at the their own risk. Now however we’ve heard from French site, Comptoir du Hardware, that Samsung have also released a new firmware. The update does however require you to format your drive and we therefore strongly recommend a backup! PB22-J owners can download the precious file here.

A whole range of Vertex 2 SSDs based on the very promising SandForce controller will soon be available from OCZ. The basic version, the Vertex 2, will be based on 34nm MLC memory and the SF-1200 version of the controller, limited to 9500 IOPS (4KB random) and will be available in 50, 100, 200 and 400 GBs. Up the range, the Vertex 2 Pro will be similar but equipped with the SF-1500 that can go up to 19000 IOPS at slightly higher speeds (280/270 MB/s reads/writes as against 270/260 MB/s). Lastly, the Vertex 2 Pro EX will use 50 nm SLC memory with the SF-1500. With identical speeds to the Vertex 2 Pro, they will be available at 50, 100 and 200 GB, the 400 GB version not possible here given the lower density of SLC memory.

OCZ told us at CES that they are increasingly looking to attack the pro market, which is more profitable, with an SSD range that will be more oriented in this direction. They were showing the PCI Express x8 Z-Drive p88 which gives impressive reads of 1300 MB/s and writes of 1200 MB/s with 14000 IOPS random reads for 4KB blocks.
There are no less than four Indilinx controllers in raid for the MLC modules that fit into SODIMM slots. This gives more flexibility to OCZ in terms of responding to the demands of certain clients and also allows easy replacement of defective modules. The p88 will be available in 512 GB, 1 TB and 2 TB versions.
