Seagate Cheetah 15K.4   Posted on 23/11/2004 at 19:00 by Marc

	Seagate has just announced the release of the 4th Cheetah hard drive generation. We remind you that Seagate released the first 15000 Rpm SCSI Cheetah hard drives in the beginning of 2000. Compared to the 15K.3, the 15K.4 hard drives have doubled platters (36.7 GB) and come in three flavours: 36.7, 73.4 and 146 GB. Sequential transfer rate is announced between 142 and 85 MB /s, instead of 86 and 52 MB /s previously. We feel that this figure is extraordinarily high. Access time has been reduced by 0.1ms to 3.5 ms for read. The SAS (Serial Attached SCSI) Ultra 320 SCSI and Fibre Channel hard drives should be released early 2005. The MTBF announced is 1.4 million of hours and is 200 000 hours higher than a 15K.3. Yes it is almost 160 years…but awkwardly the warranty is “only” five years. Seagate recommended prices for the 36.7, 73.4 and 146 GB versions are respectively $329, $659 and $1315.

ATI mobility Radeon X800   Posted on 23/11/2004 at 16:24 by Marc

	ATI announced today the release of two new laptops graphic chips, the Mobility Radeon X800 and X300. Both chips manage natively the PCI Express. The Mobility Radeon X800 has 12 pixel pipelines, 6 vertex engines and manage 256 bits memory, just like the desktop Radeon X800 Pro. The only difference between these two chips is the frequency. The Mobility is clocked at 400/400 instead of 475/450 for the X800 Pro. This chip will compete with the GeForce 6800 Go announced by NVIDIA a few days ago. The Mobility Radeon X300 has 4 pixel pipelines and 2 vertex engines. The VPU is clocked at 350 MHz and the 32 or 64 MB 64 bits memory is clocked at 300 MHz. The X600 announced a few months ago already had the same unit’s number but the VPU and the 128 Bits memory were respectively clocked at 400 MHz and 250 MHz. For the time being the only “laptops” compatible with these graphic cards are based on the i915P and the Pentium 4. The next Pentium M generation based on Intel’s Alviso will be released during the first quarter 2005. This new chipset will manage the DDR2 and PCI Express.

AMD Sempron 3000+ Mobile   Posted on 23/11/2004 at 16:11 by Marc

	AMD has announced today the release of a new Sempron dedicated to notebooks, the Sempron Mobile 3000+. Compared to the 2600+ and 2800+ clocked at 1.6 GHz and respectively equipped with 128 KB and 256 KB of cache, the 3000+ version is clocked at 1.8 GHz and is equipped with 128 KB of cache L2. Based on the Athlon 64 core, this Sempron isn’t compatible with AMD64 instructions but includes the NX Bit technology. Maximal electrical consumption reached by this 90 nm processors: 25 watts. The price: $134.

NVIDIA SLI with an ASUSTeK A8N-SLI   Posted on 23/11/2004 at 15:01 by Marc

	SLI is back! With the nForce4 and the GeForce6 6600 GT and 6800, NVIDIA has released a new version of the SLI. Are performances really doubled in practice? The answer is in this test… > Test : NVIDIA SLI with an ASUSTeK A8N-SLI
