Where Each One Wins

The data clearly shows the AMD Radeon Instinct MI60 winning both head-to-head compute benchmarks. In Geekbench OpenCL, the MI60’s 92,488 score beats the TITAN X Pascal’s 66,696 by a substantial 38.7%. In Geekbench Vulkan, the margin narrows but the MI60 still leads with 92,444 versus 77,499, a 19.3% advantage. Across both benchmarks, the MI60 wins 2 out of 2 tests.

However, the TITAN X Pascal is not without its advantages in raw specification categories that point to different strengths. The TITAN X Pascal has a higher pixel rate at 147.0 GPixel/s compared to the MI60’s 115.2 GPixel/s, indicating potential superiority in fill-rate-bound scenarios like traditional rasterization. It also has more ROPs (96 versus 64), which aligns with this pixel-pushing capability. Additionally, the TITAN X Pascal has a higher base clock of 1417 MHz versus the MI60’s 1200 MHz, though the MI60’s boost clock of 1800 MHz exceeds the TITAN’s 1531 MHz.

For workloads that depend on FP16 compute, the MI60 is the clear winner with 29.49 TFLOPS versus the TITAN’s 171.5 GFLOPS—a difference of over 170x. The MI60 also wins on texture rate (460.8 GTexel/s versus 342.9 GTexel/s) and has more shading units (4096 versus 3584) and TMUs (256 versus 224). In memory-intensive tasks, the MI60’s 1.02 TB/s bandwidth dwarfs the TITAN’s 480.4 GB/s, making it better suited for large datasets.

Architecture Differences

The fundamental architectural split is process technology and compute design. The AMD Radeon Instinct MI60 is built on TSMC’s 7 nm process, packing 13,230 million transistors into a 331 mm² die, resulting in a transistor density of 40.0M per mm². It uses the Vega 20 chip with GCN 5.1 architecture, released in November 2018 as part of the Radeon Instinct (MIx) generation. The NVIDIA TITAN X Pascal uses TSMC’s 16 nm process with 11,800 million transistors on a larger 471 mm² die, giving a density of 25.1M per mm². It employs the GP102 chip with Pascal architecture, released in August 2016 as part of the GeForce 10 generation.

The MI60’s memory subsystem is fundamentally different: HBM2 on a 4096-bit bus versus GDDR5X on a 384-bit bus. This explains the massive bandwidth gap (1.02 TB/s versus 480.4 GB/s) and capacity difference (32 GB versus 12 GB). The MI60 also supports PCIe 4.0 x16, while the TITAN X Pascal is limited to PCIe 3.0 x16.

Shader and compute capabilities diverge sharply. The MI60 has 4096 shading units and supports FP16 at a 2:1 ratio, meaning it can process half-precision floating point at twice the FP32 rate. The TITAN X Pascal has 3584 shading units and handles FP16 at a severely reduced 1:64 ratio, making it essentially FP32-focused. Neither card has dedicated ray tracing or tensor cores, as both predate those specialized units.

The TITAN X Pascal does have a higher pixel rate (147.0 GPixel/s) and more ROPs (96 versus 64), suggesting its Pascal architecture was optimized for classic rasterization throughput. The MI60 counters with higher texture rate (460.8 GTexel/s) and more TMUs. Both cards share the same dual-slot form factor and 1x 6-pin + 1x 8-pin power connectors, but the MI60 draws 300 W versus 250 W.

Throughput rates: MI60 hits 115.2 GPixel/s and 460.8 GTexel/s; TITAN achieves 147.0 GPixel/s and 342.9 GTexel/s. FP32: 14.75 TFLOPS versus 10.97 TFLOPS. FP16: 29.49 TFLOPS versus 171.5 GFLOPS.

Power and physical: MI60 TDP is 300 W with 700 W suggested PSU; TITAN TDP is 250 W with 600 W suggested PSU. Both are dual-slot, 267 mm long, and roughly 111-112 mm tall, but the TITAN is 40 mm wide versus the MI60’s unspecified width. Bus interface: PCIe 4.0 x16 versus PCIe 3.0 x16. Display outputs: MI60 has 1x mini-DisplayPort 1.4a; TITAN has 1x DVI, 1x HDMI 2.0, 3x DisplayPort 1.4a. APIs: both support DirectX 12 (12_1) and OpenGL 4.6, but MI60 supports Vulkan 1.3 while TITAN supports Vulkan 1.4.

Production status is end-of-life for both. The MI60’s predecessor is FirePro Data Center, while the TITAN’s predecessor is GeForce 900 and its successor is GeForce 20.

Head-to-Head Benchmarks

The Geekbench OpenCL test shows the most dramatic separation. The AMD Radeon Instinct MI60 scores 92,488, while the NVIDIA TITAN X Pascal scores 66,696. This 38.7% delta is the largest single performance gap in the dataset. In absolute terms, the MI60 is ahead by 25,792 points. This result aligns with the MI60’s higher FP32 throughput (14.75 versus 10.97 TFLOPS) and vastly larger memory bandwidth (1.02 TB/s versus 480.4 GB/s), which are critical for OpenCL compute workloads.

The Geekbench Vulkan test narrows the gap but still favors the MI60. The MI60 scores 92,444 against the TITAN X Pascal’s 77,499, a 19.3% advantage (14,945 points). Interestingly, the TITAN X Pascal’s Vulkan score is much closer to its OpenCL score (77,499 versus 66,696, a 16.2% improvement), while the MI60’s Vulkan score is nearly identical to its OpenCL score (92,444 versus 92,488, a 0.05% difference). This suggests the TITAN X Pascal benefits more from Vulkan’s lower overhead, but the MI60’s raw compute power still dominates.

The MI60’s nearest rivals in overall average score include the NVIDIA RTX A4500 at 91,671 (0.9% behind) and the AMD Radeon Pro VII at 97,131 (4.8% ahead). The TITAN X Pascal’s nearest rivals are the AMD Radeon Pro Vega 64 at 72,379 (0.4% behind) and the AMD Radeon Vega Frontier Edition at 73,370 (1.7% ahead). These comparisons show that while the TITAN X Pascal is competitive within its generation, the MI60 operates in a higher performance tier, closer to professional workstation cards.

Neither card shows any ray tracing or tensor core benchmark data, as neither has those hardware units. The MI60’s FP16 capability (29.49 TFLOPS) versus the TITAN’s (171.5 GFLOPS) is the single largest functional disparity, making the MI60 over 170 times faster in half-precision workloads—a critical factor for AI and machine learning inference tasks.

The Verdict

The data points to a clear split in intended use cases. The AMD Radeon Instinct MI60 is the superior choice for compute-heavy tasks, particularly those involving FP16 math, large memory footprints, or high-bandwidth data movement. Its 32 GB of HBM2 with 1.02 TB/s bandwidth, combined with 29.49 TFLOPS FP16 throughput, makes it suitable for scientific simulation, AI training, and large-scale data processing. The 38.7% OpenCL lead over the TITAN X Pascal confirms this dominance in general-purpose compute.

The NVIDIA TITAN X Pascal, while losing both compute benchmarks, has a higher pixel rate (147.0 versus 115.2 GPixel/s) and more ROPs (96 versus 64). This suggests it could be preferable for traditional 3D rendering workloads that are fill-rate limited, such as high-resolution gaming or viewport rendering. Its lower TDP (250 W versus 300 W) and more display outputs (5 versus 1) also make it more practical for a desktop workstation setup.

For users who prioritize raw compute performance, especially in OpenCL or FP16 workflows, the MI60 is the data-backed choice with a 28.3% higher average benchmark score (92,466 versus 72,098). For those whose primary workload is pixel-pushing rasterization or who need multi-display output, the TITAN X Pascal’s higher pixel rate and ROP count offer a distinct advantage, despite its lower compute scores. The choice hinges on whether the workload is compute-bound or fill-rate-bound.
