Specification Differences

The two cards differ across nearly every measurable specification. The GTX 460 SE uses the GF104 chip with Fermi architecture, while the RTX PRO 6000 uses GB202 with Blackwell 2.0. Process nodes differ dramatically: 40 nm versus 5 nm. Transistor counts are 1,950 million versus 92,200 million, and die sizes are 332 mm² versus 750 mm². Transistor density improves from 5.9M to 122.9M per mm².

Memory configurations are completely different: 1024 MB of GDDR5 versus 96 GB of GDDR7. Bus widths go from 256 bit to 512 bit, and bandwidth jumps from 108.8 GB/s to 1.79 TB/s. The GTX 460 SE has 288 shading units, 48 TMUs, and 32 ROPs, while the RTX PRO 6000 has 24,064 shading units, 752 TMUs, and 192 ROPs. The RTX PRO 6000 adds 188 RT cores and 752 tensor cores, which the GTX 460 SE lacks entirely.

Clock speeds vary by measurement: the GTX 460 SE lists only memory clock at 850 MHz (3.4 Gbps effective), while the RTX PRO 6000 lists base clock of 1,590 MHz, boost of 2,617 MHz, and memory clock of 1,750 MHz (28 Gbps effective). Pixel rates are 7.800 GPixel/s versus 502.5 GPixel/s, and texture rates are 31.20 GTexel/s versus 1,968.0 GTexel/s. FP32 compute goes from 748.8 GFLOPS to 126.0 TFLOPS. The RTX PRO 6000 also supports FP16 at 126.0 TFLOPS with 1:1 ratio, a feature absent from the GTX 460 SE.

Power requirements scale accordingly: 150 W TDP with 2x 6-pin connectors and 450 W suggested PSU for the GTX 460 SE, versus 600 W TDP with 1x 16-pin connector and 1000 W suggested PSU for the RTX PRO 6000. Both are dual-slot cards, but dimensions differ: 210 mm length for the GTX 460 SE versus 267 mm length, 111 mm height, and 40 mm width for the RTX PRO 6000. Bus interfaces are PCIe 2.0 x16 versus PCIe 5.0 x16. Display outputs are 2x DVI and 1x mini-HDMI 1.3a versus 4x DisplayPort 2.1b. API support differs with DirectX 12 (11_0) versus 12 Ultimate (12_2), and Vulkan is absent on the GTX 460 SE but present at version 1.4 on the RTX PRO 6000.

Head-to-Head Benchmarks

Direct head-to-head benchmark comparisons between these two cards are not available, as no common test was run on both. The GTX 460 SE was evaluated using Geekbench OpenCL, scoring 6,389, while the RTX PRO 6000 was evaluated using 3DMark Steel Nomad DX12, scoring 5,996. These tests measure fundamentally different workloads: OpenCL compute versus DirectX 12 graphics rendering.

In the Geekbench OpenCL test, the GTX 460 SE's score of 6,389 ties it exactly with the NVIDIA GeForce GTX 580M. It outperforms the AMD Radeon Pro WX 4100 by 0.9% and the AMD Radeon R7 M350 by 1.0%. The nearest rival, the NVIDIA RTX PRO 5000 72 GB Blackwell, scores 6,407, which is 0.3% higher than the GTX 460 SE. This indicates that in pure OpenCL compute, the Fermi architecture's 288 shading units and 748.8 GFLOPS FP32 performance remain competitive with much newer hardware.

In the 3DMark Steel Nomad DX12 test, the RTX PRO 6000's score of 5,996 is nearly identical to the NVIDIA GeForce GTX 770M at 6,000 (0.1% difference) and the AMD Radeon RX 6400 at 6,001 (0.1% difference). It edges out the AMD FirePro W4100 by 0.2% and the NVIDIA Quadro K4000M by 0.2%. This suggests that the RTX PRO 6000's massive compute resources—126.0 TFLOPS FP32 and 1,968.0 GTexel/s texture rate—do not translate into a dominant 3DMark score at this particular resolution and settings profile.

The benchmark data reveals a paradox: the older card's percentile rank (37th) is slightly higher than the newer card's (34th), yet the newer card possesses 168 times the FP32 compute throughput. This discrepancy stems from the different benchmark methodologies. Geekbench OpenCL tends to favor memory bandwidth and compute unit efficiency, where the GTX 460 SE's 108.8 GB/s and 288 cores perform adequately. 3DMark Steel Nomad DX12 tests advanced rendering features like ray tracing and mesh shaders, where the RTX PRO 6000's capabilities may be throttled or underutilized at the test's specific workload. The RTX PRO 6000's 188 RT cores and 752 tensor cores are designed for server workloads, not necessarily consumer gaming benchmarks.
