NVIDIA GeForce 945M vs NVIDIA TITAN V CEO Edition Comparison

# The Verdict - who should pick which, strictly from the data

The database places the NVIDIA TITAN V CEO Edition and the NVIDIA GeForce 945M in very different tiers. The TITAN V CEO Edition sits at the 45th percentile of all GPUs tested, with an average benchmark score of 9037. The GeForce 945M sits slightly lower, at the 42nd percentile, with an average score of 8099. The gap between them is 938 points, or roughly 11.6%. That is a substantial margin in raw performance. The data suggests a simple conclusion: if the workload is heavy and sustained, the TITAN V CEO Edition is the stronger part. If the workload is light, thermally constrained, or mobile, the 945M is the more sensible choice. The 945M is a Maxwell-based mobile part with a 75 W TDP, while the TITAN V CEO Edition is a 250 W desktop-class card with a dual-slot cooler. Those are fundamentally different products.

The benchmark results show the TITAN V CEO Edition ahead in the aggregate, but the nearest rival data tells a more nuanced story. The TITAN V CEO Edition is 0.2% ahead of the NVIDIA GeForce GTX 660, and 0.2% ahead of the NVIDIA GeForce GTX 560. It trails the AMD Radeon 550X by 1.3% and the AMD Radeon 890M by 1.9%. This places it in a crowded mid-range pack, not a decisive leadership position. The 945M, meanwhile, is 0.4% ahead of the NVIDIA GRID K2 and 0.4% ahead of the AMD Radeon R9 M360, while trailing the NVIDIA GeForce GTX 650 Ti Boost by 0.4% and the NVIDIA GeForce GTX 950M by 0.4%. Both parts sit close to the middle of the sample, and neither is a top-tier performer.

Where Each One Wins

Looking at the benchmark distribution, the TITAN V CEO Edition wins in applications that stress raw compute throughput. The recorded FP32 figure is 14.90 TFLOPS and FP16 reaches 29.80 TFLOPS (2:1). Memory bandwidth is 868.4 GB/s, and pixel rate is 186.2 GPixel/s with a texture rate of 465.6 GTexel/s. The 945M cannot match these figures; its FP32 is 1,305.6 GFLOPS, memory bandwidth is 28.80 GB/s, pixel rate is 16.32 GPixel/s and texture rate is 40.80 GTexel/s. For high-resolution rendering, large dataset processing, or any workload where raw compute is the limit, the TITAN V CEO Edition is the clear winner.

The 945M wins where power and physical constraints dominate. The 945M is a MXM module with no external power connectors, and it is designed for notebooks. The TITAN V CEO Edition is a dual-slot card with two external power connectors, requiring a 600 W power supply. It is a desktop part. In a laptop or small form factor system, the 945M is the only one of the two that fits at all. The TITAN V CEO Edition also has a production status of end-of-life, while the 945M is end-of-life as well; both are no longer in active production. The 945M fits the GeForce 900M generation slot, and its predecessor is the GeForce 800M. The TITAN V CEO Edition precedes the GeForce 20 series and follows the GeForce 900 series.

Architecture Differences

The two GPUs come from different architectures and are built on different processes. The TITAN V CEO Edition uses the GV100 chip, Volta architecture, built on a 12 nm process at TSMC. It packs 21,100 million transistors on a 815 mm² die, for a density of 25.9 million transistors per mm². The GeForce 945M uses GM107, a Maxwell architecture GPU, built on a 28 nm process at TSMC. It has 1,870 million transistors on a 148 mm² die, giving a density of 12.6 million per mm². The TITAN V CEO Edition is a much larger and denser chip.

The compute resources are also vastly different. The TITAN V CEO Edition has 5120 shading units, 320 texture mapping units, 128 ROPs, and 640 tensor cores. The 945M has 640 shading units, 40 texture units, and 16 ROPs. The TITAN V CEO Edition also has a much larger memory subsystem: 32 GB of HBM2 on a 4096-bit bus, with a bandwidth of 868.4 GB/s. The 945M has 2 GB of DDR3 on a 128-bit bus, with a bandwidth of 28.80 GB/s. That is a 30x difference in memory bandwidth in the TITAN's favor.

The two also differ in display outputs. The TITAN V CEO Edition offers one HDMI 2.0 port and three DisplayPort 1.4a outputs. The 945M is "Portable Device Dependent", so it has no fixed display outputs. API support also breaks down: the TITAN V CEO Edition supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The 945M supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.4.
