The flagship of NVIDIA’s mobility lineup the GeForce GTX 880M has been leaked along with its specifications by Notebook Review. According to this information the GeForce GTX 880M will be based on the current Kepler architecture.
Last month we revealed the details on NVIDIA’s 800M series when it was leaked by vendor Clevo. The first tier chips in the lineup are based on the MXM design which means they will be interchangeable, upgradable and even offer SLI support. The first tier MXM chips are as follows:
- GeForce GTX 880M 8 GB / N15E-GX-A2
- GeForce GTX 870M 6 GB / N15P-GT
- GeForce GTX 860M 4 GB / N15P-GX
Next are the entry level models which will feature an onboard design which means the chips are soldered to the board. So no upgrading will be possible. The entry level models are as follows.
- GeForce GTX 860M 2 GB GDDR5 / N15P-GX
- GeForce GTX 850M 2 GB DDR3 / N15P-GT
- GeForce GT 840M 2 GB DDR3 / N15S-GT1
It looks like both AMD’s new mobility chip (M290X) and NVIDIA’s will be rebrands, which is pretty disappointing. We are guessing the reason for this is that the new chips are either to power hungry or cannot be properly integrated into notebooks at this time.
Looking at the specifications the GeForce GTX 800M is basically the same as the GTX 680M and GTX 780M with 1536 CUDA cores, 128 TMUs and 32 ROPs, although it has some improvements. The VRAM has been expanded to 8 GB GDDR5 and the clock speeds have been improved up to 954 MHz base and 933 MHz boost. The memory is clocked at the same 5 GHz (effective) speed and runs across a 256-bit interface giving it 160 GB/s of bandwidth.
The expected performance boost should be between 10-15% in most usage cases. Here are some benchmark results from 3DMark.
3DMark 11 Performance Score – P8230 Marks
3DMark Firestrike – 5366 Marks
3DMark CloudGate – 19250 Marks
3DMark IceStorm – 93569 Marks
