Introducing AMD’s Radeon 7000M and NVIDIA’s GeForce 600M Mobile GPUsby Jarred Walton on December 7, 2011 2:45 AM EST
NVIDIA’s GeForce 600M Parts
We just covered the AMD side of things, but yesterday NVIDIA quietly refreshed their entry-level and midrange mobile GPUs in a similar manner. We weren’t briefed on the updates, most likely because there’s not much to say. Like AMD there are three "new" 600M parts. Here’s the overview of what NVIDIA is offering, with the previous generation equivalents listed for reference.
|NVIDIA GeForce GT 635M, GT 630M, and 610M Specifications|
|GeForce GT 635M||GeForce GT 555M||GeForce GT 630M||GeForce GT 540M||GeForce 610M||GeForce 520MX|
|Memory Clock||1.8/3.6GHz DDR3/GDDR5||1.8/3.14GHz DDR3/GDDR5||Up to 900MHz (1.8GHz) DDR3||900MHz (1.8GHz) DDR3||900MHz (1.8GHz) DDR3||900MHz (1.8GHz) DDR3|
|Memory Bus Width||192/128-bit||192/128-bit||128-bit||128-bit||64-bit||64-bit|
NVIDIA has the specifications up for their 600M parts, and it appears that they’ll be doing a straight rebadge without changing the clock speeds from the 500M equivalents—in fact, they’ll even keep the craziness that is the GT 555M. The only difference we could find is that GT 635M GDDR5 variants may have slightly more memory bandwidth (or more likely is that the spec page just doesn't adequately describe the bipolar nature of the product). What they will be changing is the apparent positioning of the products. The GT 630M and 610M drop 10 points from the model number, while the GT 635M drops 20 points; that appears to leave room for future GT 640M/650M parts, though nothing has been announced as yet. We also don’t have information on pricing, but there’s a possibility that with the drop in model number the prices will also be lower.
Like the AMD 7000M launch, GeForce 600M looks to be more about marketing and product positioning than anything. Mobile GPUs are about a generation behind their desktop counterparts, so with the renaming both AMD and NVIDIA are paving the way for new high-end GPUs to replace the current HD 6990M and GTX 580M. Thus, when we see the desktop HD 7970 and GTX 680 (or whatever they end up being named), we’ll should also see HD 7970M and GTX 680M. If recent history holds, those will end up being mobile variants of HD 7700 and GTX 660 (whatever those entail).
