AMD recently took the wraps off of its latest mobile GPU series in the form of the R5 M200, R7 M200, and R9 M200 series. Currently, there is one GPU in each respective Rx M200 series including the AMD Radeon R5 M230, R7 M265, and R9 M290X. Do not get too excited, however. All of the new mobile GPUs are based on desktop versions of Volcanic Islands and not AMD's new Hawaii GPUs. As such, the Rx M200 series are essentially rebrands of the Radeon HD 8000M series (which was in turn OEM rebrands of the HD 7000M series) based around AMD's Graphics Core Next 1.0 architecture and specifically the Pitcairn GPU implementation.
All of the Rx M200 series support DirectX 11.2 Tier 1, up to 4GB GDDR5 memory, and at least 320 GCN shader cores. Informatin on the mid-range R7 M265 is scarce, but AMD has released information on the low and high end chips. Further, Computer Base has managed to put together specifications for the R5 M230 and R9 M290X. In short, the R5 M230 is a rebranded HD 8570 with higher clockspeeds and support for more memory while the R9 M290X is a rebranded HD 8970M with official support for DirectX 11.2 Tier 1 (the HD8970M technically supports it as well). A more detailed breakdown is as follows.
The R9 M290X features 1280 shaders clocked at 850MHz/900MHz (base/boost), 80 texture units, and 32 ROPs. OEMs can pair the GPU with up to 4GB of GDDR5 memory clocked at 1,200 MHz on a 256-bit bus.
The R5 M230 has 320 shaders clocked at 855MHz, 20 texture units, and 4 ROPs. This GPU can support up to 4GB of GDDR5 memory at 1,000MHz over a 64-bit bus.
Users will be able to get the new Rx M200 series graphics cards in mobile systems from Alienware, Clevo, Lenovo, and MSI. Other manufactures should pick up the new GPUs soon as well. The new series is not terribly exciting being nearly identical to the existing HD 8000M counterparts, but it does update the lineup to AMD's new naming and branding scheme. Notably, should AMD release a Hawaii-based mobile GPU, it has not left itself much room as far as naming goes (R9 M295X?).

Earlier this year (beginning of April), NVIDIA introduced the first set of mobile graphics cards in its 700M series. These were relatively low-end cards that features at most 384 CUDA cores and were based on NVIDIA's 600-series Kepler architecture.
NVIDIA is now adding higher-end mobile GPUs to the 700M family with the GTX 760M, GTX 765M, GTX 770M, and GTX 780M. These chips are still based on Kepler (600-series), but feature more CUDA cores, more memory, a wider memory bus, and faster clockspeeds. The GTX 780M is not quite the mobile equivalent to the desktop GTX 680, but NVIDIA is matching it up against AMD's 8970M GPU and claims that it can run games like Sleeping Dogs, Assassins Creed 3, and Borderlands 2 at Ultra settings (1080p). The GTX 770M is also capable of running modern games, though some detail setitng may need to be turned down.
The chart below details the various specifications and compares the new GTX 700M cards to the existing GT 700M GPUs. At the high end, NVIDIA has the GTX 780M with 1,536 CUDA cores, a base clock of 823 MHz, and 4GB of GDDR5 memory (1250 MHz) on a 256-bit bus. The GTX 770M occupies the mid-range mobile gaming slot with 960 CUDA cores, a base clock of 811 MHz, and a memory clock of 1GHz. The GTX 760M and GTX 765M have similar hardware specifications, but the GTX 765M has a higher GPU base clock of 850 MHz versus the GTX 760M's 657 MHz base clock. The low end GTX 700M GPUs (760M and 765M) feature 768 CUDA cores, a 128-bit memory bus, and memory clockspeeds of 1GHz.
|GTX 720M||GTX 735M||GT 740M||GT 750M||GTX 760M||GTX 765M||GTX 770M||GTX 780M|
|GPU Base Clock||938 MHz||889 MHz||980 MHz||967 MHz||657 MHz||850 MHz||811 MHz||823Mhz|
|Memory Clock||1000 MHz||1000 MHz||2500 MHz||2500 MHz||1000 MHz||1000 MHz||1000 MHz||1250 MHz|
Further, GPU Boost 2.0, Geforce Experience software, and NVIDIA Optimus support are features of the new GTX 700M graphics cards. You can read more about these NVIDIA technologies in this article by motherboard reviewer Morry Teitelman.
These cards are based on NVIDIA's 600-series despite the 700M moniker. They should provide OEMs with some good gaming options on the NVIDIA side of things and allow for some more competition in the gaming notebook hardware space against the existing AMD cards.
Introduction, GT 640M Basics
About two months ago I wrote an less than enthusiastic editorial about ultrabooks that pointed out several weaknesses in the format. One particular weakness in all of the products we’ve seen to date is graphics performance. Ultrabooks so far have lacked the headroom for a discrete graphics component and have instead been saddled with a low-performance version of the already so-so Intel HD 3000 IGP.
This is a problem. Ultrabooks are expensive, yet they so far are less capable of displaying rich 3D graphics than your typical smartphone or tablet. Casual gamers will notice this and take their gaming time and dollars in that direction. Early leaked information about Ivy Bridge indicates that there has been a substantial increase in graphics capability, but the information available so far is centered on the desktop. The version that will be found in ultrabooks is unlikely to be as quick.
Today we’re looking at a potential solution - the Acer Aspire Timeline Ultra M3 equipped with Nvidia’s new GT 640M GPU. This is the first laptop to launch with a Kepler based GPU. It is also an ultrabook, albeit it one with a 15.6” display. Otherwise, it isn’t much different from other products on the market, as you can see below.
This is likely to be the only Kepler based laptop on the market for a month or two. The reason for this is Ivy Bridge - most of the manufacturers are waiting for Intel’s processor update before they go to the trouble of designing new products.

The researchers over at Jon Peddie Research pushed out their results yesterday for shipments of mobile GPUs in SoC (system on a chip) platforms, and they found some interesting results. The article covers the number of shipments by the major players in the mobile device GPU space and uses those numbers to estimate the amount of market share each of the companies has using an average of all the four quarter shipment numbers. Further, they found that from Q1 2011 to Q4 2011, the number of mobile device GPUs shipped by all manufacturers had a CAGR (compound annual growth rate) of 18%. That's a fairly impressive growth rate that shows the smartphone and tablet hardware market is continuing to steadily grow.
In terms of market share, at the end of 2011 Qualcomm was leading the pack with 31.4%, and the only other manufacturer to come close to that number was Apple with 22.7%. The little Adreno GPU by Qualcomm was obviously a popular choice last year!
To make things even more interesting, they note that although Qualcomm has the highest shipment rates, it was Samsung who enjoyed the highest CAGR with a 39% growth rate (bringing them up from 9.2% in Q1 to 14.9% in Q4). Apple then followed behind Samsung's numbers with 26% CAGR. Finally, Qualcomm had the lowest percentage growth rate but maintained the highest number of shipments.
The table below shows off the relative market share for the major SoC mobile device manufacturers, as provided by Jon Peddie Research.
They further state that the mobile GPU war is really heating up, especially between Samsung, Apple, and Qualcomm, and I tend to agree. This area of the technology market is seeing some very impressive growth and is really booming as mobile GPU SoCs are continuously released and they are getting more powerful each iteration. It is an area that has a lot of competition and is growing rapidly, much like desktop computers did 10 to 20 years ago when personal computers really started to be affordable and powerful enough to take over the world (well, market share wise).
Another interesting point about the marketshare results in that of NVIDIA's shipments. With all the marketing behind the Tegra SoC and its popularity in high end smartphones and tablets, I was under the impression that they had a lot more marketshare than they do such that when I first saw the JPR chart, I did a double take and had to be sure I read them correctly! It will be interesting to see how they do this year and whether they will start to see increased growth.
It will be interesting to see if Samsung can catch up to Qualcomm and whether or nor Qualcomm will still be the heavyweight champion by 2012. Nvidia is still just breaking into this market but they have a very powerful GPU, so it will be interesting to see just how much they manage to grow this year. What are your thoughts on these numbers? How do you think things will unfold this year? Let us know in the comments below!

Before you start to get too excited when you read about the AMD Radeon 7000M announcement today; realize this is a rebranding of Turks and Caicos, not the arrival of Southern Islands. While AMD might disappoint, at least the performance of the chips has been increased; NVIDIA went for a straight rebadge. Even if you squint, the stats for the GT630M are the same as the GT540M and same with the 610M and 520MX. There looks to be a slight difference in memory bandwidth between the 635M and 555M but AnandTech is doubtful that it is truly the case.
While we still don't know the exact frequencies that the so called 7000M chips will have in the end, they will be higher than the parts that they replace and will come in two flavours. The less expensive part will be DDR3, with a DDR5 alternative for those who want a bit more performance. Read on for all the gritty details or just look at the tables below.
"We just covered the AMD side of things, but yesterday NVIDIA quietly refreshed their entry-level and midrange mobile GPUs in a similar manner. We weren’t briefed on the updates, most likely because there’s not much to say. Like AMD there are three "new" 600M parts. Here’s the overview of what NVIDIA is offering, with the previous generation equivalents listed for reference."
