NVIDIA GeForce GTX 980, GTX 970, GTX 980M and GTX 970M 3DMark performance

After hours of work, combining all the data into one piece, we can finally show you GeForce 900 and 900M performance at a glance.
Before you ask, no, we do not have any final specifications as of yet. Sure, we have our predictions, but that’s something you can find in our previous posts. Today we are only looking at synthetic performance.

GeForce GTX 900

GeForce GTX 980 4GB
First of all, we have GeForce GTX 980 scores with three different clock speeds. We were unable to confirm which clock is is the actual reference clock, so we decided to post all three. However, GTX 980 running at 1127 MHz was our point of reference. I think it’s quite clear now, that GeForce GTX 980 has: 4GB GDDR5 memory, 256 bit bus and 7 GHz memory clock. Today we are adding more info about the core clock. In our chart you can see three speeds: 1127, 1178 and 1190 MHz. It doesn’t really matter which clock you choose, because 1127 MHz were already enough to outperform all current single-gpu high-end cards. Of course, once you add more juice to 780 Ti or 290X you can actually reach GTX 980 performance. However, GTX 980 at 1.19 GHz will not be easy to beat.
Just remember, this is just synthetic scenario, 4k gaming will surely show different results.
GeForce GTX 980 SLI
We also have GTX 980 SLI score. To understand how efficiently SLI connection is operating in high performance Maxwell GPUs, we will compare parts running at the same clock speeds in 1 and 2-GPU configuration. That said, GTX980 SLI at 1178 MHz offers 59.5% scaling, which is average at best. Radeon R9 295X is still faster.
GeForce GTX 970 4GB
According to our data, GTX 970 has a core clock of 1051 MHz. So technically, it shouldn’t be a problem to add extra speed, as we already know that GM204 can easily operate at 1150-1190 frequencies. For such reason, likelihood of GTX 970 beating GTX TITAN or 290X is relatively high.

GeForce GTX 900M

GeForce GTX 980M 8GB
We are almost certain that GeForce GTX 980M has 1038 MHz GPU clock. Compared to desktop Maxwell parts, memory speed has been reduced to 1253 MHz. Still, GTX 980M has no competitor, as it offers almost 36% upgrade over GTX 880M. Neither GK104 nor Pitcairn will ever reach such performance.
It’s worth nothing that single GTX 980M is just 8% slower than 780M in SLI.
GeForce GTX 980M SLI
For unknown reason, GM204 works much better in SLI on mobile platform. We have 95+% scaling, which absolutely fantastic score. Whether this is just a well written driver or a new technology for mobile GPUs, we do not know yet.
GeForce GTX 970M 6GB
Now here’s the interesting part. GTX 970 has neither 4GB nor 8GB, it comes with 6GB memory. What it means is that GM204 (assuming this card is using one), has reduced memory bus (probably to 192b). Unlike desktop model, GTX 970M also outperforms all current mobile flagship cards, and that’s while being 20% slower than GTX 980M.

Some scores were calculated from an average of many entires.
Lastly, here are the examples of 980 and 980M entries:
