Based on the GM206, the same GPU powering the GTX 960, NVIDIA is reportedly working on their lower-end GeForce 900 series cards, the GTX 950 Ti and GTX 950.
That said, while the GTX 960 makes use of the full GM206-300, the GTX 950 variants apparently user a cut-down GM206-250 GPU, some of which will sport a lower clock speed for the non-Ti cards.
It’s possible that instead of a lowered clock speed, the GM206-250 is the GPU powering either the GTX 950 Ti or the GTX 950 while another cut-down GPU chipset powers the other.
It’s for that reason that we currently have no idea how many stream processors, texture units or ROPs each card contains.

KitGuru, however, has speculated that seeing as the GTX 960 has 1024 stream processors, and the GTX 950 Ti and GTX 950 are unlikely to have more stream processors than their bigger brother nor would it make sense to have less than the GTX 750 Ti or GTX 750 (the cards they replace), they probably reside somewhere in the middle.
KitGuru is guessing 896 and 768 stream processors for the GTX 950 Ti and GTX 950 respectively, and we think they’re probably right on the money. WCCF Tech suggests something very similar.

Even in a case where the new 900 series cards struggle to outperform the older 700 series cards they replace, as Maxwell 2 chipsets rather than Maxwell 1, they will fully support technologies like DirectX 12.1, OpenGL 4.3, OpenCL 1.1, H.265 (HEVC) encoding and decoding, HDCP 2.2 content protection and more. The older Maxwell cards did not.
In terms of performance, you might want to take a look at the GTX 960 as a point of reference. Expect less frame rates than what the GTX 960 can manage:
| 1,920 x 1,080 (1080p) | GTX 960 |
| Battlefield 4, Ultra, 4 x MSAA | 48.6 |
| Crysis 3, Very High, SMAA | 47 |
| Assassin’s Creed Unity, Ultra, FXAA | 43 |
| Far Cry 4, Ultra, SMAA | 50.8 |
| COD: Advanced Warfare, Max, SMAA | 86.4 |
| Ryse: Son of Rome, High, SMAA | 42.2 |
| Shadow of Mordor, Ultra, Medium Textures, no SSAA | 53.2 |
| Tomb Raider, Ultimate, FXAA | 65.7 |
| Metro Last Light Redux, Max, no SSAA | 51.5 |
We’re expecting the GTX 950 Ti to more directly compete with the AMD Radeon R7 370 (around R2600 at its cheapest according to RebelTech) and the GTX 950 to go head-to-head with the R7 360 (R1800+ according to RebelTech).
