NVIDIA GeForce RTX 5070 Ti SUPER vs NVIDIA Quadro K620 Comparison

NVIDIA’s Quadro K620 and GeForce RTX 5070 Ti SUPER represent two extremes of the GPU spectrum, yet their average benchmark scores are nearly identical. The K620, a professional Maxwell-era card, averages 6282 points, while the RTX 5070 Ti SUPER, a Blackwell 2.0 consumer flagship, averages 6270 points. This places the older card a mere 0.2% ahead in average score, a statistical tie. However, the data reveals that these two GPUs are not competitors in any practical sense; they are separated by a decade of architecture, a 305W TDP gap, and a 14 GB memory disparity. The verdict is clear: the K620 wins in legacy compatibility and low power draw, while the RTX 5070 Ti SUPER dominates in raw compute, memory bandwidth, and modern API support.

Where Each One Wins

The Quadro K620 claims victory in specific legacy and efficiency scenarios based on its benchmark results and specifications. Its Geekbench OpenCL score of 6693 and Vulkan score of 5870 are the only functional benchmarks recorded, and they contribute to an average score of 6282. This performance comes from a 45 W TDP, which requires no power connectors and a suggested 200 W PSU, making it a drop-in solution for older workstations. Its PCIe 2.0 x16 interface and single-slot, 160 mm length design further reinforce its role as a low-profile upgrade for pre-existing systems. In a head-to-head context, the K620 does not win a single benchmark category against the RTX 5070 Ti SUPER, but its 0.2% average score advantage is the only measurable win it holds.

The GeForce RTX 5070 Ti SUPER wins in every modern compute category by overwhelming margins. Its 3DMark Steel Nomad DX12 score of 6269.5 is its sole benchmark entry, but the underlying hardware tells the story. With 8960 shading units, 280 TMUs, and 96 ROPs, it delivers 43.94 TFLOPS of FP32 performance, a figure that dwarfs the K620’s 863.2 GFLOPS. Its 16 GB of GDDR7 memory on a 256-bit bus provides 896.0 GB/s of bandwidth, compared to the K620’s 2 GB DDR3 at 28.80 GB/s. The RTX card also holds wins in pixel rate (235.4 GPixel/s vs 17.98 GPixel/s) and texture rate (686.6 GTexel/s vs 26.98 GTexel/s). It is the definitive performance winner for any workload that can utilize its modern architecture.

The Verdict

For a user constrained to legacy software, the Quadro K620 is the appropriate choice. Its Maxwell architecture supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.4, which remains current for API compatibility. Its 45 W power draw is a decisive advantage for systems with limited PSU capacity, and its single-slot, fanless-adjacent design (no power connectors) fits into compact chassis. The data shows no benchmark where the K620 outperforms the RTX card, but its 0.2% average score lead is a statistical artifact of comparing a Geekbench-focused test suite against a single 3DMark run. The K620 is end-of-life, but for a basic display adapter or a secondary compute device, it remains functionally viable.

The RTX 5070 Ti SUPER is the unequivocal choice for any modern workload. Its 43.94 TFLOPS FP32 and 43.94 TFLOPS FP16 (1:1) performance is 50x higher than the K620’s FP32 output. The 896.0 GB/s memory bandwidth is 31x faster, enabling data-intensive tasks that the K620 cannot handle. It supports DirectX 12 Ultimate (12_2), a feature set the K620 lacks entirely. The 70 RT cores and 280 tensor cores add hardware acceleration for ray tracing and AI workloads, capabilities absent from the K620. With a 350 W TDP and dual-slot cooler, it requires a robust power supply and chassis space, but the performance delta justifies these requirements. The data indicates this is not a contest; it is a generational chasm.

Head-to-Head Benchmarks

Direct benchmark comparisons are impossible because the two cards share no common test suite. The K620 has Geekbench OpenCL and Vulkan scores (6693 and 5870), while the RTX 5070 Ti SUPER has a single 3DMark Steel Nomad DX12 score (6269.5). The average benchmark score is the only common metric: the K620 averages 6282, and the RTX card averages 6270, a 0.2% difference in favor of the K620. This is misleading, as the nearest rivals list for the RTX card shows it is 0.2% slower than the K620 but also 0.8% faster than the AMD FirePro W600 and 0.9% slower than the AMD Radeon R7 M350.

The biggest wins each way are derived from the specification sheets rather than shared benchmarks. The RTX 5070 Ti SUPER delivers 43.94 TFLOPS FP32, which is 50.9 times the K620’s 863.2 GFLOPS. Its pixel rate of 235.4 GPixel/s is 13.1 times higher than the K620’s 17.98 GPixel/s. The texture rate of 686.6 GTexel/s is 25.4 times higher than the K620’s 26.98 GTexel/s. Memory bandwidth is the most stark divider: 896.0 GB/s versus 28.80 GB/s, a 31.1x advantage. The K620’s only wins are the average score (6282 vs 6270) and the transistor density efficiency, which is lower at 12.6M / mm² versus the RTX card’s 120.6M / mm², indicating the older card uses more die area per transistor.
