Amd Mobility Radeon Hd 5000 Series

DirectX 11 graphics are coming shortly to a notebook nigh yous. In what must be some sort of record, AMD has gone from introducing the globe'due south offset DX11 desktop graphics card to rolling out netbook-bound derivatives in the span of well-nigh three and a half months. The new Mobility Radeon Hd 5000 serial includes three different graphics chips and a whole lineup of products serving the enthusiast, performance, and mainstream markets.

Rather than introduce each model and its specifications in prose, we'll let this handy chart (partly transcribed from AMD's slide deck) do the honors:

	Mobility Radeon HD 5800 series	Mobility Radeon Hd 5700 and 5600 series	Mobility Radeon Hard disk drive 5400 serial
Transistors	1.04 billion	626 one thousand thousand	242 meg
SPs	800	400	80
Max. core clock	700 MHz	650 MHz	750 MHz
Peak shader arithmetic	1.12 TFLOPS	572 GFLOPS	120 GFLOPS
Max. memory rate	four Gbps (GDDR5)	3.ii Gbps (GDDR5)	three.two Gbps (GDDR5)
Retention bus	128-flake	128-chip	64-chip

AMD has based the Mobility Radeon HD 5800 serial on the same twoscore-nm Juniper silicon as the desktop Radeon Hard disk 5700 series. The Mobility 5700 and 5600 series are both based on Redwood, while the 5400 series is based on Cedar. Those final 2 40-nm GPUs haven't shown up on the desktop yet, but they volition soon.

There's no trace of Cypress here, though. AMD told us it developed that chip specifically for desktop cards like the Radeon HD 5870, and it's basically as well big and too hot for laptops.

This new naming scheme might audio similar sacrilege to fans of the Mobility Radeon HD 4000 series, which matched model number series with the same GPUs every bit respective desktop products. (For case, the RV770 GPU powered both the Mobility Radeon HD 4870 and the desktop Radeon HD 4870.) With the Mobility 5000 series, AMD is now playing the same branding game as Nvidia, whose mobile GPU classification has gotten, shall we say, increasingly liberal.

On the performance side of things, the Mobility 5870 can purportedly outrun the erstwhile Mobility 4870 by nearly 10-30% at 1920×1200 in current games. That might seem a piffling counter-intuitive, since desktop Radeon Hard disk drive 5770 and 4870 cards are pretty closely matched. However, AMD says none of its customers paired the Mobility 4870 with GDDR5 retentivity like the desktop production, with nigh opting instead for slower GDDR3. Also, presumably because it has a smaller, more power-efficient GPU, the Mobility 5870 lies closer to its desktop sibling in terms of clock rates. (For reference, the desktop Radeon Hard disk drive 5770 runs at 850MHz with four.8Gbps GDDR5.)

Speaking of power efficiency, the new Mobility 5000 lineup features "improved engine and retentiveness clock scaling and clock gating," which helps lower ability consumption at idle. AMD allows real-time switching betwixt integrated and discrete graphics processors, too, and so users tin disable their discrete Radeons in order to go longer battery life. The switching technology supports both Intel and AMD platforms.

Other perks include Eyefinity hexa-brandish capability, which you'll find on Mobility 5800-, 5700-, and 5600-serial GPUs. Those who opt for Mobility 5400-series parts will be limited to quad-display setups, which yet aren't shabby by any stretch of the term. All of these GPUs also support upwards to 1GB of GDDR5 RAM, although you may see some of the lower-cease parts with smaller amounts of DDR3 or DDR2 RAM strapped to them. The selection will likely be up to laptop makers.

What about availability? AMD briefed united states on the new mobile Radeons final month, a couple of weeks earlier TSMC'southward 40-nm yields finally stabilized, so we were curious if the yield problems would bear on this line of products—and whether we could expect broad availability this quarter. AMD's Asif Rehman told us, "Nosotros have some supply constrains in Q1, and our demand is much higher than anticipated . . . though we anticipate that in Q2 and following quarters, nosotros should exist able to improve upon our supply state of affairs and be able to fully support all the demand." That said, Rehman added that AMD had already shipped "many thousands" of Mobility Radeon Hard disk drive 5800, 5700, 5600, and 5400 parts to its customers.

We had another question: does AMD programme to follow Nvidia'south lead and offer mobile graphics drivers direct? Rehman answered, "This is something that we are currently working on. I cannot give you whatsoever definite timeline in this regard, but definitely this is something that is in the pipeline, and we will announce information technology when we have back up bachelor and we accept the total qualification done on all the systems and the GPUs." Promising news, then, even if AMD is keeping a tight hat on the time frame.

Those who go shopping for a laptop subsequently this twelvemonth may see Mobility Radeon HD 5165 and 5145 graphics processors popular up in some spec sheets. No, those aren't typos—but they're not DirectX 11 mobile GPUs, either. Rather, the 5165 and 5145 are faster-clocked versions of 55-nm, DirectX ten.1 Mobility Radeon Hd 4800 and 4600 GPUs, respectively. Although we surmised that these products were somehow tied to the forty-nm shortages, AMD said it created them before the yield problems cropped up. The house'due south partners just wanted faster 55-nm parts with better brand names. Get effigy.
