NVIDIA GeForce 860M Laptop Maxwell GPU Benchmarks Appear

 NVIDIA GeForce 860M Laptop Maxwell GPU Benchmarks Appear

Currently the only two desktop product based on Nvidia's Maxwell are the GTX 750 and GTX 750 Ti. However the GeForce 800M series of mobile GPUs will obviously get Maxwell as well, and a 860M Laptop has been benchmarked. Results in 3DMark 11 show a score of a cool 5,339 points, which definitely above the previous model GeForce GTX 770M.

That places the 860M mpbile GPU say in-between a GeForce GTX 760 Ti Boost and perhaps a AMD Radeon R7 260X. The GTX 860M should be a 640 shader cores GPU with 40 TMUs (texture mapping units) and 16 ROPs (raster operating units). It will get 3 GB of GDDR5 VRAM (5.0 Gbps is tied to a 192 bits wide memory bus. From the looks of it the part is running 540 MHz.

The 860M should be pretty energy friendly alright, not bad huh ?

Don't compare it with desktop.

Score is just above GTX770M.
GTX770M (75W) which is:
192bit, 960shaders, 800MHz Core + 4GHz memory, 24/80 ROPs/TMUs
While GTX860M (35~45W based on complexity & clocks) is:
128bit, 640shaders, 540MHz Core + 5GHz memory, 16/40 ROPs/TMUs


This results in:
GTX770M:
pixel fr. 19.2GP/s, Texture fr. 64.0GT/s, mem. bandwidth 96GB/s
GTX860M:
pixel fr. 8.6GP/s, Texture fr. 18.6GT/s, mem. bandwidth 80GB/s


We can omit memory bandwidth here as it's quite similar.
But unless maxwell have same performance with 1/2 of pixel fillrate and 1/3 of texture fillrate, this score is fake.

Edit: and btw, it has 1/2 of die size and transistor count of GTX770M, which means it's dirty cheap to manufacture.

Edit2: Clock to clock comparison for performance per transistor results: 860M delivers at same clocks 2.95x higher performance per transistor than 770M.

On wcctech they Said that gpu-z doesn't read the gtx 860M right , we will see when it I'd officially release

It's usually called wccfake. Incorrect reading in GPUz looks quite different. This is likely fake as someone wants attention.
Anyway, if only single of those read values is correct (like transistor count, die size, frequency, rops, tmus, fillrates) and it gave really those 3DMArk 11P scores then this gpu should bring AMD stocks down to 0.5$ at day nVidia releases it.

But desktop Maxwell says other story :)

i think it will have the same specs as the GTX 750 TI , since TDP is around the same but the clocks should be somewhat lower. I mean 60 W GPU isn't even that hard to get into laptop since the GTX 780M is around 110 Ws. I really do hope AMD has an answer something against, a monopoly is never fun.

Next gen mid level card = current gen high end card?

The performance is impressive given the specs of the chip. However it doesn't really seem like much of an improvement over the 770M, I expected the performance to be similar to the 780M. This is definitely a win for the manufacture and it probably runs cooler too but am I incorrect in thinking that a new mid level card should have the performance level of a last generation high end card?

Have a look at the 770M's average 3Dmark11 score here:
http://www.notebookcheck.net/NVIDIA-GeForce-GTX-770M.88995.0.html

The 680M is faster than both the 770M and the 860M:

I own one too but my CPU is a little faster:
