NVIDIA Unveils Lineup of GeForce 800M Series Mobile GPUs, Many With Maxwell

MojoKid writes "The power efficiency of NVIDA's Maxwell architecture make it ideal for mobile applications, so today's announcement by NVIDIA of a new top-to-bottom line-up of mobile GPUs—most of them featuring the Maxwell architecture—should come as no surprise. Though a couple of Kepler and even Fermi-based GPUs still exist in NVIDIA's new line-up, the heart of the product stack leverages Maxwell. The entry-level parts in the GeForce 800M series consist of the GeForce GT 820M, 830M, and 840M. The 820M is a Fermi-based GPU, but the 830M and 840M are new chips that leverage Maxwell. The meat of the GeForce GTX 800M series consist of Kepler-based GPUs, though Maxwell is employed in the more mainstream parts. NVIDIA is claiming the GeForce GTX 880M will be fastest mobile GPU available, but the entire GTX line-up will offer significantly higher performance then any integrated graphics solution. The GeForce GTX 860M and 850M are essentially identical to the desktop GeForce GTX 750 Ti, save for different frequencies and memory configurations. There are a number of notebooks featuring NVIDIA's GeForce 800M series GPUs coming down the pipeline from companies like Alienware, Asus, Gigabyte, Lenovo, MSI and Razer, though others are sure the follow suit. Some of the machines will be available immediately."

      At some point enough x86/x64 patents will expire that Nvidia will be able license the remaining ones and so an x64 chip of their own.

      Or alternatively they could sell Arm+GPU SOCs instead - arguably Arm+GPU is a better bet than x64+GPU because the sales of phones and tablets will exceed the sales of x64 PCs. Of course the margins are likely to be thinner because there's a lot of competition in the Arm SOC market - Apple and Samsung have their own in house designs and outside that it looks like Qualcomm have most of the rest of the market.

      Still it's not like AMD is doing very well competing with Intel. And the reason Qualcomm do so well is because they design their own Arm microarchitectures - Scorpion and Krait were both designed in house and were higher performance than the best Arm designed microarchitecture. So I guess NVidia could be aimed to compete with Qualcomm since Denver is in house too.

      Actually Apple A6 and A7 chips are like this too. Apple have an Arm license but the chips are designed in house. So it seems like of the Arm SOCs that actually sell well only Samsung is using Arm's designs and only in some markets

      E.g.

      http://en.wikipedia.org/wiki/S...

      Galaxy S4 models use of one of two processors, depending on the region and network compatibility. The S4 version for North America, most of Europe, parts of Asia, and other countries contains Qualcomm's Snapdragon 600 system-on-chip, containing a quad-core 1.9 GHz Krait 300 CPU and an Adreno 320 GPU. The chip also contains a modem which supports LTE. Other models include Samsung's Exynos 5 Octa system-on-chip with a heterogeneous CPU. The octa-core CPU comprises a 1.6 GHz quad-core Cortex-A15 cluster and a 1.2 GHz quad-core Cortex-A7 cluster. The chip can dynamically switch between the two clusters of cores based on CPU usage; the chip switches to the A15 cores when more processing power is needed, and stays on the A7 cores to conserve energy on lighter loads

      So there are two versions. A Qualcomm Snapdragon one for the US and Europe and an Exynos one for Asia. The Exynos one uses Cortex-A15 and Cortex-A7 in a BIG.little configuration.

      Unfortunately they fucked up the big.LITTLE configuration

      http://www.anandtech.com/show/...

      The Exynos 5410 saw limited use, appearing in some international versions of the Galaxy S 4 and nothing else. Part of the problem with the design was a broken implementation of the CCI-400 coherent bus interface that connect the two CPU islands to the rest of the SoC. In the case of the 5410, the bus was functional but coherency was broken and manually disabled on the Galaxy S 4. The implications are serious from a power consumption (and performance) standpoint. With all caches being flushed out to main memory upon a switch between CPU islands. Neither ARM nor Samsung LSI will talk about the bug publicly, and Samsung didn't fess up to the problem at first either - leaving end users to discover it on their own.

      You can see the results here

      http://www.gsmarena.com/samsun...

      The Qualcomm one has much better talk time - almost twice as much.

      You have to wonder what the hell has happened to Arm to be honest. It seems like Apple (A6, A7) and Qualcomm (Scorpion, Krait) do a much better job at Arm core design than Arm/Samsung.

      It'll be interesting to see battery life tests on the Snapdragon 801 and Exynos 5422 versions of the S5 to see if Samsung have got big.LITTLE working like it is supposed to. Actually I wonder whether big.LITTLE is even necessary - it seems like it would be much easier to just

      I'm with the others not understanding what you're on about with monitors, but indeed additional cooling is useful. The thing is no matter how efficient the CPU and GPU are, it's a product of the watt budget and how the laptop is designed. Depends on the thickness/thinness, heatsinks and fans, build quality etc. so it's really on a laptop per laptop basis.

      Modern stuff also throttles, it gets slower when needed so the laptop won't melt itself, that plays in both sides..
