While Nvidia’s flagship card for laptops, GeForce GTX 480M, was announced in May and is available in several gaming laptops, info about the rest of the 400M series was scarce. But finally, Nvidia has announced the rest of the GeForce 400M series:
- High end: GTX 480M (already launched), GTX 470M, GTX 460M.
- Performance and mainstream: GT 445M, GT 435M, GT 425M, GT 420M, GT 415M.
- Entry level: Jarred at AnandTech talks about the GT 415M as the entry level, and he rejoices about its high performance compared to the current GeForce 310M, but I think the gap is too large and probably Nvidia has a 410M or similar, closer in performance to the 310M.
You can see the specs of the cards and a good analysis of them at AnandTech. All 400M series cards are based on Fermi and they support DirectX 11, OpenGL 4.0, Optimus, PhysX, CUDA, DirectCompute, OpenCL, HD video decoding (H.264/VC1/MPEG2/Blu-ray) and HDMI 1.4a.
Some things I find noteworthy:
- GeForce GT 445M comes in two versions, with very different bandwidths. We need some benchmarks to see what difference that makes in games, but the impact on performance could be quite big and the “slow” version of the GT 445M could be only a bit faster than the GT 435M. So, if you are looking at a laptop sporting the GT 445M, try to find out what version of the card does it have.
- GTS cards are absent at this moment.
Performance-wise, Nvidia talks about the 400M series being a 40% faster than 300M parts, but we will have to wait a bit to see some benchmarks. Optimus support for high-end cards is good news, hopefully next-generation gaming laptops would have a much better battery life than current models.
We don’t know anything about ATI’s Mobility 6000 series, but desktop parts should be launched in the next few months, and ATI usually launches laptop parts not much later than desktop ones. Anyway, Nvidia has a few months of advantage, because Asus has already announced several laptops that are available at Xotic PC: N51JQ, N73Jq, G53Jw and G73Jw.
