News site DailyTech has gotten its paws on AMD's upcoming ATI Radeon HD 4890 videocard from an undisclosed source based in Taiwan, and has thus been able to confirm rumored details of the new card's spec sheet.
Built around the RV790 core, the Radeon HD 4890, as received by DailyTech, comes with a core clock of 850MHz . The site also reports 1GB of GDDR5 memory running at 3,900MHz resulting in 124.8 GB/s of bandwidth. Final memory specs could change, however, as the card DailyTech received came with Qimonda chips, which declared insolvency (went bankrupt) back in January 2009.
No word yet on a projected price point or release date, but not to be outdone, Nvidia plans to go head-to-head with ATI's 4890 with its GeForce GTX 275. According to reports, the upcoming GTX 275 is being built around the G200b GPU core with 240 shader processors chugging along at 1,404MHz. Other specs include 80 texture units, 30 render back ends, and a 448-bit memory interface. GPU and memory clockspeeds are expected to debut at 633MHz and 2,322MHz, respectively.
Look for the GTX 275 to launch on April 9, 2009 for somewhere between $230 and $280.
Windows 7 is already feeling the love from both graphics camps. Earlier this month, Nvidia released a specialized Forceware driver for the beta OS along with the promise of regular updates, and now AMD has followed suit with its new ATI Catalyst 9.3 driver this week. However, the new Catalyst driver rolls both Windows 7 and Vista support into a single download, allowing the company to lay claim as offering the "first unified driver installation package to incorporate Windows 7 support." AMD says future Catalyst releases will also be unified for both the current and upcoming Windows OSes.
"AMD's expertise in visual computing shines through in the combined experience of Windows 7 and ATI Radeon graphics," said Anantha Kancherla, group manager responsible for Windows graphics, Microsoft. "With today's release of a Windows 7 unified driver, AMD once again demonstrates its ability to deliver perfromance and cutting-edge driver support."
Hit the jump to find out what else to expect from the new Catalyst 9.3 unified driver.
Four-monitor support in a single-slot, low-profile, half-length videocard? You betcha. That's exactly what AMD's offering up with the release of its professional ATI FirePro 2450 multi-view graphics card.
"The ATI FirePro 2450 offers the reliability professionals expect and the efficiency IT departments require. IT managers want a card they can test once, deploy virtually anywhere, and count on to run reliably,” said Janet Matsuda, senior director, AMD Professional Graphics. “The low power consumption enables cool, energy-efficient operation, as well as superior reliability and longevity. The compact form factor can be deployed in nearly any system. This accelerator is perfect for customers who need more than two displays, such as in financial services and process control."
The FirePro 2450 comes equipped with 512MB of GDDR3 memory, variable speed fan sink, maximum resolution of 1920 x 1200, DirectX 10.1 and OpenGL 2.1 support, native PCI-E x16 and x1, and support for up to four independent DVI or VGA monitors.
According to AMD, the new card consumes less than 18W on average for 2D business usage, and no more than 32W when fully stressed.
The ATI FirePro 2450 is available now with an MSRP of $499.
Word on the web is that Nvidia will release its GTS 250 videocard sometime this week, which is essentially a rebranded 9800 GTX+. Nvidia's latest GeForce drivers -- WHQL 182.08 -- adds support for the upcoming card, while also extending SLI profile support for some newly released games.
Nvidia claims up to double-digit performance gains in handful of games with the new drivers versus 181.22, including up to 11 percent in Left 4 Dead at high resolution with AA, up to 10 percent in F.E.A.R. 2: Project Origin, and up to 10 percent in Race Driver: GRID at high resolution and AA.
The latest release also fixes a bug in Vista 32-bit with dual-GeForce 8600 GT videocards that prevented the Fluid Demo (using PhysX) from running while using hardware acceleration when SLI is enabled. Good thing too, lest anyone second guess investing in two 8600 GT cards.
Nvidia has said on more than one occasion that it wants to simplify its product line to make it easier for consumers who might not know the difference between, say, an 8800 GTS 256MB, 8800 GTS 512MB, and 8800 GTS 640MB, and why the 512MB trumps them both. Then there's the 9800GTX+, which is a supercharged 9800 GTX, which is really a supercharged G92-based 8800 GTS, which is confusing as all get-out.
It gets better. Meet the GeForce GTS 250, the videocard formerly known as the 9800 GTX+. The rebranded videocard still uses the 55nm G92b GPU, however in a more mature yielding chip in GTS 250 trim. Available in both 512MB and 1GB configurations, the latter includes a new board design noticeably smaller than the 9800 GTX+ by about an inch and a half.
Other specs include a 738MHz core clockspeed, 1100MHz memory clockspeed, 256-bit memory interface for a 70.4 GB/s of total memory bandwidth, 16 ROPs, 64 texture filtring units, and 128 processor cores. The GTS 250 carries a TDP of 150 watts, and according to Anandtech's testing, both idle and load power consumption runs about 30W less than the 9800 GTX+.
The 512MB and 1GB versions will run $130 and $150 respectively, with widespread availability expected next week.
Talk about a true desktop replacement - Asus' new W90 laptop packs enough hardware inside to leave most mainstream desktop PCs in the dust. It's also one of Asus' first notebooks to boast an 18.4-inch LCD display, and at that size, it better (and it does) support full HD with a 1920x1200 resolution.
The W90 comes with a speedy Intel Core 2 Duo T9600 processor (2.8GHz, 6MB cache, 1066MHz frontside bus) on the Intel X38 chipset, complimented with 6GB of DDR2-memory, a 320GB hard drive, and DVD burner. But it's the graphics that really makes the W90 a desktop replacement for gamers. The 11.46-pound lappy owes some of its bulk to a dual-GPU ATI 4870 X2 videocard with 1GB of video memory - sweet!
As is expected, the W90 doesn't come cheap, and is available now for $2,200 through Newegg.com. That also includes a backpack, mouse, and 12-cell battery.
ATI has been eerily quiet regarding the company's first 40nm-based graphics release, code named RV740, and instead letting rumors swirl around the web. That's okay, because review site Guru3d managed to snag a sample of an as-yet un-named RV740-based videcoard and has put it through a variety of DX9 and DX10 benchmarks.
On the hardware front, Guru3d says the new part comes equipped with 640 shaders, 32TMUs, and 16 ROPs. If this sounds familiar, it's because these are the same specs as those found on the RV770LE, only the RV740 bumps up both the core frequency from 575MHz to 650 MHz, and memory frequency from 1800MHz to 3200MHz. The wide gap in memory frequency can be attributed to the use of GDDR5, compared to RV770LE's GDDR3. But are the higher frequencies enough to make up for the smaller 128-bit memory bus on the RV740?
According to Guru3d, the answer is yes. The new card fell in between in the Radeon HD 4830 and HD 4850 in every benchmark the site published, no matter whether it was tested at 1280x1024 or 2560x1600. Not at all bad for a card that is expected to sell for under $100, however there's been no official word yet on price.
In what the company claims is a first (and as far as we can tell, they're right), Palit Microsystems has released a GeForce GTX 285 videocard outfitted with 2GB of memory. Every other GTX 285 currently ships with 1GB.
Whether or not the additional memory buffer proves a worthwhile investment remains to be seen, but it's worth noting the GTX 285 is Nvidia's fastest single-GPU solution available, second in speed only to the dual-GPU GTX 295. We've often seen graphics partners outfit lower end cards with additional memory, which is almost always of dubious value, but that isn't the case here.
Palit also lays claim to offering the first custom designed GTX 285. Deviating from the reference heatsink/fan assembly, Palit has outfitted its GTX 285 series with two PWM fans and four heat pipes.
"Conceived for two GPUs, the two PWM fans are able to provide sufficient air flow to cool GPU on the graphics quietly," Palit wrote in a press release. "The PWM fan created for both fans can adjust the fan speed depending on the GPU's temperature."
Palit also offers the GTX 285 in a more standard 1GB configuration. No word yet on pricing or availability for either model.
Nvidia this week released new WHQL GeForce drivers for GeForce 6, 7, 8, 9, and 200-series owners. The new drivers, version 182.06, promise around a 10 percent performance increase in Fallout 3 at high resolution with AA, F.E.A.R. 2: Project Origin, Half Life 2 at high resolution with AA, the insanely entertaining Left 4 Dead at high resolution with AA, and Race Driver: GRID, also at high resolution with AA.
In addition to double-digit performance boosts, Nvidia says its new drivers include full support for OpenGL 3.0 on GeForce 8, 9, and 200 series GPUs and automatically installs the new PhysX software (version 9.090203. The drivers also fix a bug in Vista 32-bit where GeForce 9800 GTX/GX2/GT/GTX+ and 8800 GTS/GT/GS owners experienced a system hang when switching between performance states.
Diamonds might be a girl's best friend, but Sparkle's Diamonds Sputtering technology looks to cozy up to videocards in an attempt to offer better heat dissipation.
The company today announced the new technology, which it says consists of outfitting the cooling fins on videocards with a Diamond-like Carbon (DLC) membrane. According to Sparkle and its R&D team, DLC offers high heat conduction capable of dissipating heat much more effectively than copper alone.
"The diamonds do heat dissipation four times faster than copper, it relies on the phonons which is produced by the crystal lattice vibration, to bring heat to lower temperature places," Sparkle wrote in its press release. "Diamond-like Carbon can achieve both functions at the same time, that is, transferring heat to lower temperature places with both graphite metal bond and diamond insulation bond (the covalent bond)."
It gets even more technical and goes on to discuss the process of Plasma Enhanced CVD (PECVD) to plate the DLC membrane on videocards, but the end result is a 5C temperature reduction on a 9500GT, according to Sparkle. But don't hold your breath for diamond-cooled videocards any time soon. Sparkle admits the technology carries a "high" cost and is still mulling over bringing DLC to market.
