GPU Comparison

NVIDIA TITAN Xp and AMD Radeon RX 460 occupy opposite ends of the performance spectrum, and the benchmark data reflects a chasm rather than a contest. The TITAN Xp wins every shared test by a staggering margin, yet the RX 460 remains a distinct product with its own purpose. This analysis splits the two by workload, architecture, and raw numbers, leading to a clear verdict: the TITAN Xp is a compute and high-resolution beast, while the RX 460 is a low-power entry point with no shared benchmark victory.

Where Each One Wins

The data is unambiguous: the NVIDIA TITAN Xp wins 100% of the head-to-head benchmarks, taking both available tests with deltas exceeding 300%. The AMD Radeon RX 460 wins zero shared tests. However, that does not mean the RX 460 has no role. The TITAN Xp dominates in every metric where both are measured, Geekbench OpenCL and Vulkan, but the RX 460’s design targets a different battlefield: minimal power draw and physical footprint.

The TITAN Xp’s wins are absolute. In Geekbench OpenCL, it scores 72,585 versus the RX 460’s 17,855, a 306.5% advantage. In Geekbench Vulkan, it hits 87,180 versus 20,198, a 331.6% lead. These are not close calls; they represent a multi-generational performance gap. The TITAN Xp’s average benchmark score of 19,177 places it in the 64th percentile of all GPUs, while the RX 460’s 18,373 average lands at the 62nd percentile, a surprisingly narrow average gap, but one driven by different benchmark sets. The RX 460 only has three listed benchmarks (Metal, OpenCL, Vulkan), and its OpenCL and Vulkan scores are roughly one-quarter of the TITAN Xp’s.

Where the RX 460 wins is in operational efficiency and integration. It draws 75 W TDP against the TITAN Xp’s 250 W, requires no power connectors, and fits a 170 mm (6.7 inches) length versus 267 mm (10.5 inches). That is a trade-off: the RX 460 sacrifices massive compute for a card that can run on a 250 W PSU, whereas the TITAN Xp demands a 600 W unit. For workloads that fit within 2 GB VRAM and 112 GB/s bandwidth, the RX 460 is a viable low-power option, but it cannot touch the TITAN Xp in any compute-heavy task.

Architecture Differences

The two GPUs come from different foundries and design philosophies. The TITAN Xp uses the GP102 chip on a 16 nm TSMC process, packing 11,800 million transistors into a 471 mm² die. The RX 460 uses the Baffin chip on a 14 nm GlobalFoundries process, with 3,000 million transistors on a 123 mm² die. Transistor density is nearly identical (25.1M/mm² vs 24.4M/mm²), but the TITAN Xp has nearly four times the raw silicon.

Core counts diverge sharply. The TITAN Xp has 3,840 shading units, 240 TMUs, and 96 ROPs. The RX 460 has 896 shading units, 56 TMUs, and 16 ROPs. That is a 4.3x shading unit advantage for NVIDIA. Clock speeds favor the TITAN Xp as well: 1405 MHz base and 1582 MHz boost versus 1090 MHz base and 1200 MHz boost. Memory is another gulf: the TITAN Xp uses 12 GB of GDDR5X on a 384-bit bus, delivering 547.6 GB/s, while the RX 460 uses 2 GB of GDDR5 on a 128-bit bus, at 112.0 GB/s.

Architecturally, the TITAN Xp is Pascal, the RX 460 is GCN 4.0. This explains the FP16 disparity: the TITAN Xp yields 189.8 GFLOPS (1:64 ratio), while the RX 460 offers 2.150 TFLOPS (1:1). The RX 460’s compute is balanced, but its raw FP32 is 2.150 TFLOPS versus 12.15 TFLOPS for the TITAN Xp. Pixel rate and texture rate follow: 151.9 GPixel/s and 379.7 GTexel/s for NVIDIA, versus 19.20 GPixel/s and 67.20 GTexel/s for AMD. API support is close, both hit DirectX 12 (12_1 vs 12_0) and OpenGL 4.6, but the TITAN Xp runs Vulkan 1.4 versus 1.3 on the RX 460. The TITAN Xp also has more display outputs (1x HDMI 2.0, 3x DisplayPort 1.4a) versus the RX 460 (1x DVI, 1x HDMI 2.0b, 1x DisplayPort 1.4a).

Head-to-Head Benchmarks

The shared benchmark pool is small, only two tests, but the results are decisive. In Geekbench OpenCL, the TITAN Xp scores 72,585 against the RX 460’s 17,855. That is a 306.5% delta, meaning the TITAN Xp is roughly four times faster. This test stresses general compute, and the TITAN Xp’s 12.15 TFLOPS FP32 and 547.6 GB/s bandwidth crush the RX 460’s 2.150 TFLOPS and 112.0 GB/s.

In Geekbench Vulkan, the gap widens slightly. The TITAN Xp posts 87,180 versus 20,198, a 331.6% delta. Vulkan leverages the TITAN Xp’s higher boost clock (1582 MHz) and larger memory subsystem. The RX 460’s score is still respectable for its class, but it cannot compete with a card that has 12 GB of GDDR5X and a 384-bit bus.

The TITAN Xp’s other benchmark results reinforce its dominance, though they have no RX 460 counterpart. Passmark G3D shows 18,750, GPU compute 9,430, and DirectX 9 scores 226. The RX 460’s only other data point is Geekbench Metal at 17,065, which the TITAN Xp does not list. For context, the TITAN Xp’s nearest rivals are the GTX 780 (avg 19,164, delta 0.1%), Tesla K20m (19,089, 0.5%), and RTX 4050 Mobile (19,049, 0.7%). The RX 460’s rivals include the Arc A770M (18,383, -0.1%) and FirePro D500 (18,533, -0.9%). These rival lists show that the TITAN Xp sits at the top of its peer group, while the RX 460 is mid-pack among low-power cards.

The Verdict

Pick the NVIDIA TITAN Xp if you need maximum compute throughput. The data shows a 306.5% lead in OpenCL and 331.6% in Vulkan, with 12.15 TFLOPS FP32 and 547.6 GB/s bandwidth. It is for workloads that demand 12 GB VRAM and a 384-bit bus, think large datasets, high-resolution textures, or GPU compute. Its 64th percentile ranking and average score of 19,177 place it above the RX 460’s 62nd percentile and 18,373 average, despite the RX 460 having fewer benchmarks.

Pick the AMD Radeon RX 460 if you need a low-power, compact card. It draws 75 W, requires no power connectors, and fits a 250 W PSU. It is 170 mm long, making it suitable for small cases. The RX 460’s 2 GB VRAM and 112 GB/s bandwidth are limiting, but its 1:1 FP16 ratio (2.150 TFLOPS) is a niche advantage for specific compute tasks. However, the data offers zero shared benchmark wins, so there is no scenario where the RX 460 outperforms the TITAN Xp in the same test.

The verdict is not a close call. The TITAN Xp is an end-of-life flagship with a 1,199 USD launch MSRP, and the RX 460 is an end-of-life budget card with no MSRP listed. If you have the power budget and the workload, the TITAN Xp wins every measurable way. If you need efficiency and minimal footprint, the RX 460 exists, but it loses every shared benchmark.

The TITAN Xp leads in every performance specification except FP16 ratio, where the RX 460’s 1:1 ratio offers a theoretical compute advantage for FP16 workloads, though its absolute FP32 is far lower. The RX 460’s only other wins are physical: no power connectors, lower TDP, and a shorter length.
