Quadro 2200m variants

I hav a dell m4700 looking to upgrade with a 2200m however noting complicting part numbers on ebay etc. can anybody confirm the rationale for the model numbers?

i.e. Nvidia Quadro M2200M N15P-Q5-A2
Nvidia Quadro M2200M N17P-Q3-A1

Cheers

 

N15P-Q5-A2 is a K2200M, which is a Kepler Model, a lot older and weaker than a M2200M.

 

wonderful thanks for explaining!

 

Deleted.

 

K2200M is an oddity. It is indeed a good bit weaker than the M2200... But, despite its name, it is actually a Maxwell card (GM107 chip) and it is still supported by current NVIDIA drivers, unlike the main Kepler mobile Quadro series (K2000M, K2100M, etc.).

 

Oh, that's curious, I didn't know that. Thanks for clarify.

As I can see here, it's like a M2000M with 2 GB, is that correct? If so, maybe this could be a viable option depending exclusively on the cost.

 

Looks like K2200M and M2000M have the same number of CUDA cores. The vRAM is different as you said (2 GB vs 4 GB). K2200M also appears to be capped at a much lower clock speed... but probably is overclockable with a vBIOS mod or something (assuming that there is also not a strict power limit).

 

They might be the Quadro equivalents of the GTX 860M and 960M, which were both GM107.

 

Indeed... And also GeForce GTX 870M and 880M are actually Kepler cards
(Actually looks like 860M was released with both GM107 and GK104 versions.)

 

One of the reasons why NVIDIA skipped over the 800-series on the desktop, because it was a mess on mobile... 840M, 850M and 860M were Maxwell, with 860M also having a Kepler version; 870M and 880M were Kepler. The GM107 chip overclocked by a lot, though: my old Clevo gained something like 25% performance with a +300 MHz overclock.
