NVIDIA GeForce GTX 770M vs NVIDIA RTX PRO 6000 Blackwell Server Comparison

The Verdict

The data presents a striking anomaly: despite a twelve-year gap in release dates, a 28 nm versus 5 nm process node, and a 36-fold difference in transistor count, the NVIDIA GeForce GTX 770M and the NVIDIA RTX PRO 6000 Blackwell Server land at nearly identical average benchmark scores. The GTX 770M averages 6000 points, while the RTX PRO 6000 Blackwell Server averages 5996 points, a delta of just 0.1%. According to the nearestRivals data, these two cards are effectively tied, with the GTX 770M sitting a mere 0.1% ahead of its Blackwell counterpart. This is a bizarre juxtaposition; the benchmark database suggests that a 2013 mobile GPU and a 2025 server-class accelerator are equivalent in the specific tests recorded here. The verdict from a pure score perspective is that neither wins; they are statistical equals.

However, the specification sheet tells a completely different story. The RTX PRO 6000 Blackwell Server is an active, current-generation product with 24064 shading units, 188 RT cores, and 752 tensor cores, while the GTX 770M is an end-of-life part with 960 shading units and no dedicated ray tracing or tensor hardware. The data implies that for any workload beyond the specific benchmark tests listed, the Blackwell part would be in a different universe of performance. The Verdict, strictly from the numbers, is that a buyer seeking a modern, feature-rich compute card should choose the RTX PRO 6000 Blackwell Server, as it is the only one with active production status and contemporary API support. The GTX 770M, with its DirectX 12 (11_0) support and lack of RT/tensor cores, is only relevant for legacy compatibility or very specific low-power scenarios. The data forces a question: why do these two disparate GPUs have nearly identical scores? The answer likely lies in the benchmark types, with the GTX 770M's scores coming from Geekbench Metal and OpenCL tests, while the RTX PRO 6000's score comes from a single 3DMark Steel Nomad DX12 test. These are not comparable apples-to-apples workloads.

Where Each One Wins

Looking strictly at the benchmark wins, the GTX 770M has a narrow victory in the aggregate. It achieves a 0.1% higher average score than its Blackwell rival, and its benchmark suite includes two distinct tests (Geekbench Metal at 3448 and Geekbench OpenCL at 8552), showing a balanced performance profile across different compute APIs. The RTX PRO 6000 Blackwell Server has only one recorded benchmark result (3DMark Steel Nomad DX12 at 5996), which is its sole data point. In terms of use-case split, the GTX 770M appears to win in OpenCL compute scenarios based on its 8552 score, which is substantially higher than its Metal score, suggesting a strength in general-purpose GPU compute tasks that leverage OpenCL. The RTX PRO 6000 Blackwell Server, with its 3DMark Steel Nomad result, is validated for a modern DirectX 12 Ultimate workload, indicating its strength in contemporary gaming or DXR-enabled rendering paths. The data shows no other victories; the head-to-head benchmark list is empty, and the wins counter is zero for both. This means the "wins" are entirely derived from the aggregate average score, where the GTX 770M edges ahead. For a server product, the RTX PRO 6000 Blackwell Server's 96 GB of GDDR7 memory and 1.79 TB/s bandwidth are far superior for large data sets, but no benchmark score exists to quantify that advantage. The GTX 770M wins in the narrow metric of average benchmark score, but the RTX PRO 6000 Blackwell Server wins on every architectural metric that would matter for modern professional workloads, even if the recorded scores do not reflect it.

Architecture Differences

The architectural gap between these two GPUs is immense, as evidenced by the fact pack. The GTX 770M is built on the Kepler architecture using the GK106 chip, manufactured on a 28 nm process at TSMC, with 2,540 million transistors on a 221 mm² die. Its transistor density is a modest 11.5 million per mm². In contrast, the RTX PRO 6000 Blackwell Server uses the Blackwell 2.0 architecture with the GB202 chip, also from TSMC but on a 5 nm process, packing 92,200 million transistors onto a 750 mm² die, achieving a density of 122.9 million per mm². This is a generational leap in manufacturing technology. The core configuration differs drastically: the GTX 770M has 960 shading units, 80 texture mapping units, and 24 ROPs, while the RTX PRO 6000 Blackwell Server has 24064 shading units, 752 TMUs, and 192 ROPs. Critically, the Blackwell part introduces 188 RT cores and 752 tensor cores, which are entirely absent from the Kepler design. Clock speeds also differ, with the GTX 770M boosting to 797 MHz versus the RTX PRO 6000's boost of 2617 MHz. Memory architecture is another divide: the GTX 770M uses 3 GB of GDDR5 on a 192-bit bus, yielding 96.19 GB/s, while the RTX PRO 6000 Blackwell Server uses 96 GB of GDDR7 on a 512-bit bus, achieving 1.79 TB/s. The pixel rate is 15.94 GPixel/s versus 502.5 GPixel/s, and texture rate is 63.76 GTexel/s versus 1,968.0 GTexel/s. The FP32 compute is 1.530 TFLOPS versus 126.0 TFLOPS, an 82-fold difference. The RTX PRO 6000 also has FP16 capability at 126.0 TFLOPS (1:1), while the GTX 770M has no listed FP16 performance. The API support also separates them; the GTX 770M supports DirectX 12 (11_0) and Vulkan 1.2.175, while the Blackwell card supports DirectX 12 Ultimate (12_2) and Vulkan 1.4. The process node, transistor count, and core features all point to the RTX PRO 6000 Blackwell Server being architecturally superior in every measurable way, yet the benchmark scores say otherwise, which is a fascinating discrepancy.

Head-to-Head Benchmarks

The head-to-head benchmark list is empty, meaning there are no direct comparison tests between these two specific GPUs in the fact pack. However, we can analyze their individual scores to understand their relative performance. The GTX 770M's Geekbench OpenCL score is 8552, which is its strongest result, while its Geekbench Metal score is 3448. The RTX PRO 6000 Blackwell Server's only score is 5996 from the 3DMark Steel Nomad DX12 test. When comparing these numbers, the GTX 770M's OpenCL score of 8552 is significantly higher than the RTX PRO 6000's 3DMark score of 5996, suggesting that in a raw compute scenario, the older card outperforms the newer one in this specific test. Conversely, the RTX PRO 6000's 3DMark score of 5996 is higher than the GTX 770M's Metal score of 3448, indicating that in modern graphics workloads, the Blackwell card is superior. The average benchmark score, which combines these results, places the GTX 770M at 6000 and the RTX PRO 6000 at 5996, with the deltaPct showing the GTX 770M is 0.1% ahead. The biggest win for the GTX 770M is in the OpenCL test, where its score is 5104 points higher than the RTX PRO 6000's 3DMark score. The biggest win for the RTX PRO 6000 Blackwell Server is in the 3DMark test, where its score is 2548 points higher than the GTX 770M's Metal score. These numbers are surprising given the architectural disparity, but they highlight that the benchmark types are measuring different aspects of performance, and the GTX 770M's OpenCL result is a notable outlier that boosts its aggregate score.
