ATI RV740 Performance Figures Leaked
Christo [PCD] , Monday 02 March 2009 - 23:58:10 //

Benchmarks place it comfortably between the HD4830 and HD4850

Despite an uncharacteristically tight-lipped stance from ATI on its first 40nm parts, hardware review website Guru of 3D has managed to secure a sample of an RV740-based graphics card and put it through the paces. At first glance, the specifications suggest that it is little more than a shrunken RV770LE core, but a closer look reveals several improvements

According to the preview published today, the GPU boasts 640 shaders, 32 TMUs, and 16 ROPs; all the same as the RV770LE. However, the core and memory clocks both receive a significant bump, up from 575MHz to 650MHz and 1800MHz GDDR3 to 3200MHz GDDR5 respectively. The substantial boost in memory frequency works to offset the performance difference incurred by the smaller 128-bit memory bus on the RV740, which brings the reported math processing rate for the GPU up to 900 GigaFLOPS.

Every single benchmark result published in the review places the RV740-based card right between the existing Radeon HD4830 and HD4850 graphics cards, also from ATI. For example, at 8xMSAA and 16xAF in the popular first person shooter Left 4 Dead, the RV740 turns in 28 FPS, flanked by scores of 25 and 30FPS from the two cards at 2560x1600 resolution. The card does exhibit a significant performance drop at higher resolutions, likely the result of the 128-bit memory bus width and the relatively low 512MB of memory. Other reported benchmarks include Far Cry 2, Crysis WARHEAD, Call of Duty 5: World at War, Brothers in Arms: Hell’s Highway, and 3DMark Vantage.

MSRP for RV740-based graphics cards is expected to be $99 USD, which should make it a very attractive offering in the upper-mainstream segment. While the official name of the video card has not been released, the author of the article suspects it would be called the Radeon HD4750, which would be a logical name for a card with the given characteristics.

Dell Unveils Studio XPS 435 Desktop
Christo [PCD] , Wednesday 25 February 2009 - 20:55:55 //

The new Studio XPS 435 is Dell's flagship multimedia desktop

Dell is one of the largest computer manufacturers in the world and sells numerous notebook and desktop computers for different uses. Dell purchased the Alienware brand a few years ago, but the company still makes gaming machines under its own XPS brand. However, not all of the computers under the XPS brand are aimed at gamers; some of the machines are for multimedia enthusiasts.

Dell has announced a new multimedia desktop called the Studio Desktop XPS 435. The desktop computer uses the Intel Core i7 CPU with triple-channel DDR3 RAM. Dell says the machine can be optioned with up to 24GB of RAM and up to 4.5TB of storage.

A variety of CPUs available are up to the Core i7 965 Extreme Edition and all systems use the Intel X58 chipset. Operating system choices include Vista Home Premium 64-bit and Vista Ultimate 64-bit. The mainboard used by Dell has six user accessible DIMM slots.

Graphics card options available for the system include the Radeon ATI HD 4870 with GDDR5 RAM. Onboard sound comes via Intel 7.1 HD audio while a Creative SoundBlaster X-Fi sound card is an option. Dell offers a Blu-ray option and DVD burners are also available. The mainboard offers a single x16 PCI-E slot, so dual graphics isn’t an option for the XPS 435. The machine also features a built-in IR receiver for control via a media center remote.

The power supply offers 475W of power and the chassis is tool-less for easy upgrades. Two colors are available including white and translucent black.

Dell is mum on the pricing for the system for the moment, but details should be available soon.

Samsung's 7Gb/s GDDR5 in 50nm Mass Production, Targets 40nm GPUs
Christo [PCD] , Thursday 19 February 2009 - 21:44:18 //

Could this mean mainstream GDDR5?

Korean DRAM giant Samsung has been making a lot of technology announcements recently. It touted its high density 4Gb DDR3 chips last month, and showed off its advanced 40nm process for producing 2Gb DDR3 that it plans to introduce by the end of the year.

One area of sales that it hasn't been as successful as it would like has been in the GDDR5 market, designed for use in high-end video cards. Most graphics cards have been using Qimonda's GDDR5 chips, which are both faster and cheaper than GDDR4 memory.

However, Qimonda's insolvency presents a unique market opportunity for Samsung to take the lead. It has put its latest 7Gb/s GDDR5 design into mass production on its recently introduced 50nm-class process, which it has been using to produce more cost effective DDR3 DRAM.

Samsung says its GDDR5 will provide up to 28GB/s bandwidth, more than doubling GDDR4's 12.8GB/s. It will be available in 32Mbx32 or 64Mbx16 configurations, summing up to a 1Gb density.

Both Advanced Micro Devices and NVIDIA are currently working on 40nm die shrinks of their most powerful GPUs. AMD is planning to shift lower-speed GDDR5 downstream to its mainstream graphics cards, which currently use GDDR3 and DDR3 memory. It will then use the latest high-spec GDDR5 chips for its newest and most powerful video cards.

Samsung noted that it was able to tweak its 50nm process so much that it increased its production efficiency by a hundred percent over its 60nm process. If true, this will cut prices low enough that GDDR5 will be able to finally move into mainstream video cards.

Meanwhile, Samsung stated that while it has plans to extend 50nm production across its entire graphics memory product line, it expects that GDDR5 memory chips will capture more than 50 percent of the high-end PC graphics market by 2010.

Intel Wants Its CPUs to be the Cloud's Silver Lining
Christo [PCD] , Wednesday 18 February 2009 - 20:25:11 //

Intel looks covetously at the cloud computing market for its server processors

The future of large data centers may look very different from the data centers of today. In the future, the data center is expected to be cloud-based and could save companies with large server farms millions of dollars.

Intel is watching the move to cloud computing closely and wants its processors to be at the heart of the cloud computing movement. Intel says that 20 to 25% of its server processors could be dedicated to data centers using cloud computing by 2012.

Intel's Jason Waxman said, "We expect to see, by 2012, a substantial portion of the server market will be running some version of cloud computing. Right now, as much as 14 percent of server purchases are going into some sort of cloud deployment."

Even the largest Fortune 500 companies are expected to begin migrating to cloud computing to grab the massive cost savings that cloud computing can generate. Intel says that cloud computing can save a company 10% in power usage for a large data center equating to a savings of about $6 million in some instances. At the same time software optimization of the same servers could save an additional $20 million.

Intel isn’t alone in coveting the cloud server market though and will have competition from AMD whose server processors are very popular in virtualized applications. Intel is betting on features like its Dynamic Power Node Manager to woo large enterprises to its products for power savings, which equate into big monetary savings for the companies.

Waxman said, "The cloud has promise, but we’re trying to be pragmatic. With small to medium-sized businesses, companies are asking, ‘Do I need lots of infrastructure, or can I do software as service?’ And the enterprise is cautious. They’re thinking that now’s the time to start the evaluation and path to it, as opposed to just jumping in."

Intel Sues NVIDIA Over Chipset Manufacturing
Christo [PCD] , Wednesday 18 February 2009 - 20:04:30 //

NVIDIA says Intel is trying to slow the uptake of NVIDIA platforms

Intel and NVIDIA have had agreements in place that allow NVIDIA to build chipsets that support Intel processors. The two firms recently began licensing NVIDIA technology for use on Intel motherboards as well.

Today reports are coming in that Intel has filed a suit against NVIDIA alleging that the licensing agreement in effect does not allow NVIDIA to build chipsets for Intel processors with integrated memory controllers -- including the Nehalem CPUs.

According to Bit-Tech, Intel issued a statement saying, "Intel has filed suit against NVIDIA seeking a declaratory judgment over rights associated with two agreements between the companies. The suit seeks to have the court declare that NVIDIA is not licensed to produce chipsets that are compatible with any Intel processor that has integrated memory controller functionality, such as Intel’s Nehalem microprocessors and that NVIDIA has breached the agreement with Intel by falsely claiming that it is licensed. Intel has been in discussions with NVIDIA for more than a year attempting to resolve the matter but unfortunately we were unsuccessful. As a result Intel is asking the court to resolve this dispute."

NVIDIA feels confident that its license agreement does in fact allow it to build chipsets for Intel processors with integrated memory controllers. So confident in fact that according to NVIDIA it will not change its roadmap and will continue development of chipsets for the Intel processors in question and for future Intel processors.

NVIDIA points out that this license disagreement does not affect any of its currently shipping products and the graphics giant doesn't expect any impact to its current business regardless of the outcome.

NVIDIA has released an official statement saying, "NVIDIA believes that our bus license with Intel clearly enables us to build chipsets for Intel CPUs with integrated memory controllers. We are aggressively developing new products for Intel’s current front side bus (MCP79 and MCP89) and for Intel’s future bus, DMI."

NVIDIA maintains that the suit is nothing but an attempt by Intel to slow the adoption of NVIDIA platforms and protect a decaying CPU business where the CPU has become much less relevant compared to the GPU inside a PC.
