AMD Radeon R9 M265X vs NVIDIA TITAN V CEO Edition Comparison

# Head-to-Head Benchmarks

The benchmark data presents an unusual comparison, as these two GPUs were never tested under the same benchmark suite. The NVIDIA TITAN V CEO Edition has PassMark G2D and G3D scores of 1086 and 16988 respectively, while the AMD Radeon R9 M265X has a single Geekbench OpenCL score of 8851. With no overlapping tests, direct numeric comparison is impossible; however, the available figures and percentile ranks provide context.

The TITAN V CEO Edition's PassMark G3D score of 16988 places it in the 45th percentile of all GPUs, with an average benchmark score of 9037. Its nearest rivals include the NVIDIA GeForce GTX 660 (avg score 9022, deltaPct 0.2), the NVIDIA GeForce GTX 560 (avg score 9058, deltaPct -0.2), the AMD Radeon 550X (avg score 8918, deltaPct 1.3), and the AMD Radeon 890M (avg score 9210, deltaPct -1.9). These tight deltas—all within roughly 2%—suggest that in the aggregate benchmark context, the TITAN V CEO Edition sits in a crowded performance band despite its massive specifications.

The Radeon R9 M265X's Geekbench OpenCL score of 8851 places it in the 44th percentile, just one percentile point below the TITAN V CEO Edition. Its nearest rivals are the AMD Radeon Pro WX 5100 (avg score 8863, deltaPct -0.1), the AMD Radeon 550X (avg score 8918, deltaPct -0.8), the NVIDIA GeForce RTX 3050 A Mobile (avg score 8746, deltaPct 1.2), and the NVIDIA GeForce GTX 460 v2 (avg score 8743, deltaPct 1.2). The R9 M265X's average benchmark score of 8851 is actually slightly lower than the TITAN V CEO Edition's average of 9037—a margin of about 2.1%—yet both GPUs land within one percentile point of each other in the overall distribution.

The most striking takeaway is that the TITAN V CEO Edition, despite being an end-of-life product from 2018 with a 250 W TDP, a 32 GB HBM2 memory pool, and 5120 shading units, achieves an average benchmark score that is only marginally higher than the R9 M265X from 2014 with 640 shading units and 2 GB GDDR5. This suggests that the TITAN V CEO Edition's raw compute capabilities—14.90 TFLOPS FP32 versus 800.0 GFLOPS for the R9 M265X—do not translate into proportional benchmark dominance in the aggregate metrics tracked here. The PassMark G3D score of 16988 for the TITAN V CEO Edition is substantial in absolute terms, but its percentile ranking of 45 indicates that many other GPUs score higher.

# Architecture Differences

The architectural gap between these two GPUs is generational and fundamental. The NVIDIA TITAN V CEO Edition uses the GV100 chip built on a 12 nm process at TSMC, with 21,100 million transistors on an 815 mm² die, yielding a transistor density of 25.9 million per mm². The architecture is Volta, part of the GeForce 10 generation, and it includes 5120 shading units, 320 texture mapping units, 128 raster operation pipelines, and 640 tensor cores. The Radeon R9 M265X, by contrast, uses the Venus chip on a 28 nm process at TSMC, with 1,500 million transistors on a 123 mm² die, giving a transistor density of 12.2 million per mm². Its architecture is GCN 1.0, part of the Gem System (R9 M200) generation, with 640 shading units, 40 TMUs, and 16 ROPs.

The memory subsystems are vastly different. The TITAN V CEO Edition features 32 GB of HBM2 memory on a 4096-bit bus, delivering 868.4 GB/s of bandwidth. The R9 M265X has 2 GB of GDDR5 on a 128-bit bus, with 64.00 GB/s of bandwidth. This represents a 13.6x difference in memory bandwidth—a decisive factor for memory-bound workloads. The TITAN V CEO Edition's memory clock is 848 MHz (1696 Mbps effective), while the R9 M265X runs at 1000 MHz (4 Gbps effective).

Clock speeds also diverge sharply. The TITAN V CEO Edition has a base clock of 1200 MHz and a boost clock of 1455 MHz. The R9 M265X operates at a 575 MHz base and 625 MHz boost—less than half the TITAN's base clock. The TITAN V CEO Edition's pixel rate is 186.2 GPixel/s and texture rate is 465.6 GTexel/s, versus 10.00 GPixel/s and 25.00 GTexel/s for the R9 M265X.

The TITAN V CEO Edition supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The R9 M265X supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The TITAN V CEO Edition also includes tensor cores—640 of them—which the R9 M265X lacks entirely. The TITAN V CEO Edition's FP16 throughput is 29.80 TFLOPS (2:1 ratio), while the R9 M265X has no listed FP16 capability.

# Where Each One Wins

The TITAN V CEO Edition wins decisively in raw compute performance. Its FP32 throughput of 14.90 TFLOPS is 18.6x higher than the R9 M265X's 800.0 GFLOPS. For any workload that scales with shading units, texture units, or memory bandwidth, the TITAN V CEO Edition holds an overwhelming advantage. The 5120 shading units versus 640, the 320 TMUs versus 40, and the 128 ROPs versus 16 all point to superior fill-rate and geometry processing capabilities. The 868.4 GB/s memory bandwidth versus 64.00 GB/s means large datasets, high-resolution textures, and compute-heavy shaders will run dramatically faster on the TITAN V CEO Edition.

The R9 M265X wins in efficiency of design for its target segment. Built on a 28 nm process with only 1,500 million transistors, it achieves a 44th percentile ranking with a fraction of the silicon budget. Its die size of 123 mm² versus 815 mm² means it occupies 15% of the physical area while delivering an average benchmark score (8851) that is 97.9% of the TITAN V CEO Edition's average (9037). The R9 M265X also has a lower base clock (575 MHz versus 1200 MHz) and boost clock (625 MHz versus 1455 MHz), yet its percentile ranking is only one point lower.

In terms of software and API support, the TITAN V CEO Edition has a newer Vulkan version (1.4 versus 1.2.170) and a higher DirectX feature level (12_1 versus 11_1). This means the TITAN V CEO Edition can run modern graphics workloads with more advanced features, while the R9 M265X may face compatibility limitations in newer titles. The TITAN V CEO Edition also has display outputs (1x HDMI 2.0, 3x DisplayPort 1.4a), whereas the R9 M265X lists no display outputs—indicating the latter is likely intended for mobile or embedded implementations.
