NVIDIA GeForce GTX 950M vs NVIDIA GeForce GTX TITAN BLACK Comparison

Head-to-Head Benchmarks

The data in the database is unambiguous: the NVIDIA GeForce GTX TITAN BLACK dominates the NVIDIA GeForce GTX 950M in every recorded head-to-head benchmark. The two cards were tested in Geekbench OpenCL and Geekbench Vulkan, and the TITAN BLACK wins both with substantial margins.

In Geekbench OpenCL, the TITAN BLACK scores 27,218 points against the GTX 950M's 9,745 points. This is a delta of 179.3%, meaning the TITAN BLACK delivers nearly three times the compute throughput in this API. The OpenCL test stresses raw parallel processing, and the TITAN BLACK's larger execution resource pool is immediately visible in the results. The GTX 950M's score of 9,745 is not trivial, but it operates in a completely different performance class.

The Geekbench Vulkan result is even more lopsided. The TITAN BLACK posts 29,561 points, while the GTX 950M manages 6,525 points. The delta here reaches 353%, a staggering gap that indicates the TITAN BLACK is over four times faster in this workload. Vulkan is a low-overhead API that scales with raw hardware capability, and the TITAN BLACK's advantage in shading units and memory bandwidth becomes decisive. The GTX 950M's 6,525 score places it far behind, and no amount of driver optimization could close a gap of this magnitude.

Looking at the broader average benchmark scores, the TITAN BLACK holds a 9,474 average across all recorded tests, while the GTX 950M averages 8,135. That is a 16.5% advantage for the TITAN BLACK in aggregate, though the head-to-head tests show a far wider spread. The average includes tests where the GTX 950M was not measured, so the head-to-head deltas are the more reliable comparison for direct performance.

In terms of percentile ranking among all GPUs, the TITAN BLACK sits at the 46th percentile, while the GTX 950M sits at the 42nd. Both cards are in the mid-range of the database's GPU population, but the TITAN BLACK edges ahead even in this relative measure. The TITAN BLACK's nearest rivals include the NVIDIA GeForce GTX 760 (average score 9,458, delta 0.2%) and the NVIDIA Quadro K5000 (average score 9,637, delta -1.7%). The GTX 950M's nearest rivals include the AMD Radeon R9 M360 (average score 8,129, delta 0.1%) and the NVIDIA GeForce GTX 980 (average score 8,167, delta -0.4%). These rival comparisons show that each card is competitive within its own performance tier, but the tiers themselves are far apart.

Where Each One Wins

The TITAN BLACK wins every benchmark category where both cards have recorded data. It takes the Geekbench OpenCL and Geekbench Vulkan tests outright, with no countervailing win for the GTX 950M. The database records 2 wins for the TITAN BLACK and 0 wins for the GTX 950M in direct comparisons. This is a clean sweep.

The TITAN BLACK's strengths lie in compute-heavy and API-diverse workloads. Its OpenCL score of 27,218 and Vulkan score of 29,561 indicate that it handles general-purpose GPU compute and modern graphics APIs with authority. The GTX 950M, by contrast, shows a more modest profile. Its OpenCL score of 9,745 is roughly one-third of the TITAN BLACK's, and its Vulkan score of 6,525 is less than one-quarter. For users running OpenCL acceleration in content creation or Vulkan-based games, the TITAN BLACK is the clear choice.

The GTX 950M's only advantage is indirect. It has no benchmark wins, but its lower power draw and compact form factor make it suitable for portable systems. The database lists the GTX 950M as an IGP (integrated graphics processor) with a 75 W TDP and no power connectors, whereas the TITAN BLACK is a dual-slot card requiring 1x 6-pin and 1x 8-pin connectors with a 250 W TDP and a 600 W suggested PSU. For a laptop or small form factor system, the GTX 950M is the only feasible option, but that is a system integration consideration, not a performance victory.

Users who need raw throughput in compute benchmarks should choose the TITAN BLACK without hesitation. Users who need a low-power, mobile-friendly GPU should consider the GTX 950M, but they must accept a significant performance deficit in every measured workload.

Architecture Differences

The two GPUs come from different architectural generations and have fundamentally different chip designs. The TITAN BLACK uses the GK110B chip based on the Kepler architecture, built on a 28 nm process at TSMC. The GTX 950M uses the GM107 chip based on the Maxwell architecture, also on a 28 nm process at TSMC. Both chips share the same transistor density of 12.6M per square millimeter, but the physical scale differs enormously.

The TITAN BLACK's GK110B packs 7,080 million transistors on a 561 mm² die. The GTX 950M's GM107 contains 1,870 million transistors on a 148 mm² die. The TITAN BLACK has roughly 3.8 times the transistor count and a die that is 3.8 times larger. This scale difference explains the performance gap: more transistors, more shading units, more memory interface width.

The TITAN BLACK features 2,880 shading units, 240 texture mapping units, and 48 raster operation units. The GTX 950M has 640 shading units, 40 TMUs, and 16 ROPs. The TITAN BLACK's shading unit count is 4.5 times higher, its TMU count is 6 times higher, and its ROP count is 3 times higher. These are not incremental differences; they are generationally distinct configurations.

Memory is another major divider. The TITAN BLACK uses 6 GB of GDDR5 on a 384-bit bus, delivering 336.0 GB/s of bandwidth. The GTX 950M uses 4 GB of DDR3 on a 128-bit bus, delivering 28.80 GB/s. The bandwidth difference is a factor of 11.7. The TITAN BLACK's memory clock is listed at 1750 MHz (7 Gbps effective), while the GTX 950M's is 900 MHz (1800 Mbps effective). For texture-heavy and bandwidth-sensitive workloads, the TITAN BLACK's memory subsystem is in a different league.

Clock speeds tell a different story. The GTX 950M has a higher base clock at 993 MHz versus the TITAN BLACK's 889 MHz, and a higher boost clock at 1124 MHz versus 980 MHz. The GTX 950M's Maxwell architecture achieves better clock-for-clock efficiency, but the TITAN BLACK's massive resource pool overwhelms the clock advantage. Pixel rate and texture rate confirm this: the TITAN BLACK posts 58.80 GPixel/s and 235.2 GTexel/s, while the GTX 950M posts 17.98 GPixel/s and 44.96 GTexel/s. FP32 compute is listed at 5.645 TFLOPS for the TITAN BLACK and 1,438.7 GFLOPS (roughly 1.44 TFLOPS) for the GTX 950M.

API support differs slightly. The TITAN BLACK supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.175. The GTX 950M supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.4. The GTX 950M has a newer Vulkan version, but the TITAN BLACK has a higher DirectX feature level. In practice, the TITAN BLACK's hardware advantage outweighs these API version differences.

The Verdict

The NVIDIA GeForce GTX TITAN BLACK is the superior GPU by every measured performance metric. The database shows a 179.3% lead in Geekbench OpenCL and a 353% lead in Geekbench Vulkan. Its average benchmark score of 9,474 exceeds the GTX 950M's 8,135 by 16.5%. The wins tally is 2-0 in favor of the TITAN BLACK.

The TITAN BLACK is built for desktop workstations and high-end gaming rigs. It requires a dual-slot footprint, a 250 W TDP, and external power connectors. It was released on 2014-02-17 with a launch MSRP of 999 USD. Its production status is end-of-life, and it belongs to the GeForce 700 generation, succeeding the GeForce 600 and preceding the GeForce 900.

The GTX 950M is a mobile-class GPU. It was released on 2015-03-12, belongs to the GeForce 900M generation, and has no launch MSRP recorded. It draws only 75 W, uses no power connectors, and operates as an IGP. It is end-of-life as well, with the GeForce 800M as its predecessor and GeForce 10 Mobile as its successor.

Pick the TITAN BLACK if you need maximum compute throughput in OpenCL or Vulkan workloads, or if you are building a desktop system with adequate power delivery and cooling. The data shows no scenario where the GTX 950M outperforms it. Pick the GTX 950M only if your system constraints, such as a laptop chassis or a low-wattage power supply, preclude the TITAN BLACK entirely. The GTX 950M is a capable mobile GPU, but it is not a competitor to the TITAN BLACK in raw performance.
