Q: Which card has newer architecture and manufacturing process?

A: The RTX PRO 6000 Blackwell uses the Blackwell 2.0 architecture on a 5 nm TSMC process, while the GTX 770 uses the Kepler architecture on a 28 nm TSMC process. The RTX PRO 6000 also packs 92,200 million transistors on a 750 mm² die, versus 3,540 million transistors on a 294 mm² die for the GTX 770.

Q: What memory configurations do these cards have?

A: The RTX PRO 6000 Blackwell has 96 GB of GDDR7 memory on a 512-bit bus with 1.79 TB/s bandwidth. The GTX 770 has 2 GB of GDDR5 memory on a 256-bit bus with 224.4 GB/s bandwidth.

Q: Which card supports ray tracing and tensor cores?

A: Only the RTX PRO 6000 Blackwell has dedicated ray tracing cores (188) and tensor cores (752). The GTX 770 has neither, as its Kepler architecture predates those features.

Q: What is the production status of each card?

A: The RTX PRO 6000 Blackwell is Active, released on March 17, 2025. The GTX 770 is End-of-life, released on May 29, 2013, with the GeForce 900 series as its successor.

Architecture Differences

The RTX PRO 6000 Blackwell and the GeForce GTX 770 come from opposite ends of NVIDIA's product timeline, separated by more than a decade of architectural evolution. The RTX PRO 6000 uses the GB202 chip built on the Blackwell 2.0 architecture, fabricated on a 5 nm TSMC process. The GTX 770 uses the GK104 chip on the Kepler architecture, fabricated on a 28 nm TSMC process. The process shrink alone allows the newer card to fit 92,200 million transistors into a 750 mm² die, giving a transistor density of 122.9 million per square millimeter. The GTX 770's 3,540 million transistors on a 294 mm² die yield just 12.0 million per square millimeter.

The compute resource gap is enormous. The RTX PRO 6000 has 24,064 shading units, 752 texture mapping units, and 192 ROPs. The GTX 770 has 1,536 shading units, 128 TMUs, and 32 ROPs. The RTX PRO 6000 also adds 188 ray tracing cores and 752 tensor cores, hardware that simply does not exist on the Kepler-based GTX 770. This makes the newer card capable of hardware-accelerated ray tracing and tensor workloads, while the GTX 770 relies entirely on traditional rasterization.

Clock speeds tell a different story. The RTX PRO 6000 runs at a base clock of 1590 MHz and boosts to 2617 MHz, while the GTX 770 operates at 1046 MHz base and 1085 MHz boost. The newer card's higher clocks, combined with far more shaders, produce a massive throughput advantage. The RTX PRO 6000 delivers 126.0 TFLOPS of FP32 compute and the same 126.0 TFLOPS for FP16, whereas the GTX 770 manages only 3.333 TFLOPS of FP32 and has no listed FP16 capability.

Memory architecture also diverges sharply. The RTX PRO 6000 uses 96 GB of GDDR7 on a 512-bit interface, reaching 1.79 TB/s of bandwidth. The GTX 770 uses 2 GB of GDDR5 on a 256-bit interface, reaching 224.4 GB/s. That is roughly an 8x difference in memory capacity and a similar multiplier in bandwidth. The RTX PRO 6000 also supports PCIe 5.0 x16, while the GTX 770 is limited to PCIe 3.0 x16.

Power and physical design reflect the performance gap. The RTX PRO 6000 has a 600 W TDP with a single 16-pin connector and a suggested 1000 W power supply. The GTX 770 has a 230 W TDP with one 6-pin and one 8-pin connector and a suggested 550 W power supply. Both are dual-slot cards, but the RTX PRO 6000 is longer at 304 mm versus 267 mm, taller at 137 mm versus 111 mm, and slightly thicker at 40 mm versus 38 mm. Display outputs differ as well: the RTX PRO 6000 offers four DisplayPort 2.1b outputs, while the GTX 770 offers two DVI, one HDMI 1.4a, and one DisplayPort 1.2.

Head-to-Head Benchmarks

Direct head-to-head benchmark results between these two cards are not available in the database, as they were never tested in the same workload. Instead, the database records separate benchmark suites for each card. The RTX PRO 6000 Blackwell was tested in 3DMark Steel Nomad DX12, scoring 16,408. The GTX 770 was tested in three Geekbench workloads: Metal (9,369), OpenCL (15,707), and Vulkan (19,166), averaging 14,747.

The RTX PRO 6000's single result places it at the 59th percentile among all GPUs tracked by the database. Its nearest rival, the AMD Radeon PRO W7500, scores nearly identically at 16,415, a 0% delta. The AMD Radeon RX 5700 XT is 0.3% ahead at 16,361, and the AMD Radeon Pro 5600M is 16,351 at 0.4% ahead. The only rival that beats it meaningfully in percentile terms is the NVIDIA GeForce RTX 5090 D V2, which scores 16,504 at 0.6% behind, putting the RTX PRO 6000 slightly ahead of that card by that margin.

The GTX 770 sits at the 57th percentile. Its nearest rival, the AMD Radeon RX 5500 XT, averages 14,692 at 0.4% ahead. The NVIDIA Quadro M2000 averages 14,532 at 1.5% ahead of the GTX 770. The GTX 770 beats the NVIDIA GeForce GTX 660 Ti by 2.1% (15,063) and the AMD Radeon Pro 560X by 11% (15,082, which is 2.2% behind the GTX 770). The GTX 770's average score of 14,747 is roughly 10% below the 16,408 of the RTX PRO 6000, a gap that is consistent with the generational leap in shader count, memory bandwidth, and compute throughput.

Interpretation of these numbers requires caution because the benchmark suites differ. The RTX PRO 6000's 16,408 in 3DMark Steel Nomad DX12 is a modern DirectX 12 workload that stresses ray tracing and mesh shaders, features the GTX 770 cannot accelerate. The GTX 770's Vulkan score of 19,166 is its strongest showing, exceeding its OpenCL result by over 3,400 points and its Metal result by nearly 10,000 points. That Vulkan score actually surpasses the RTX PRO 6000's Steel Nomad result in raw point terms, but the tests are not directly comparable.

Specification Differences

The two cards differ in nearly every specification field recorded by the database. Process node: 5 nm versus 28 nm. Transistors: 92,200 million versus 3,540 million. Die size: 750 mm² versus 294 mm². Transistor density: 122.9 million per mm² versus 12.0 million per mm².

Clock speeds: base 1590 MHz versus 1046 MHz, boost 2617 MHz versus 1085 MHz, memory clock 1750 MHz (28 Gbps effective) versus 1753 MHz (7 Gbps effective). Memory: 96 GB GDDR7 versus 2 GB GDDR5, 512-bit versus 256-bit bus, 1.79 TB/s versus 224.4 GB/s bandwidth.

Compute hardware: 24,064 shading units versus 1,536, 752 TMUs versus 128, 192 ROPs versus 32, 188 RT cores versus none, 752 tensor cores versus none. Pixel rate: 502.5 GPixel/s versus 34.72 GPixel/s. Texture rate: 1,968.0 GTexel/s versus 138.9 GTexel/s. FP32: 126.0 TFLOPS versus 3.333 TFLOPS. FP16: 126.0 TFLOPS versus not specified.

Where Each One Wins

The RTX PRO 6000 Blackwell wins decisively across nearly all compute-oriented metrics. Its 126.0 TFLOPS FP32 performance is roughly 38 times the GTX 770's 3.333 TFLOPS. Pixel rate and texture rate are similarly one-sided: 502.5 GPixel/s versus 34.72 GPixel/s, and 1,968.0 GTexel/s versus 138.9 GTexel/s.

For workloads that leverage ray tracing or tensor operations, the GTX 770 has no hardware support at all, so the RTX PRO 6000 wins by default. The 96 GB of GDDR7 memory with 1.79 TB/s bandwidth makes it suitable for massive datasets, large model inference, and high-resolution rendering, none of which the 2 GB GTX 770 can accommodate.

The GTX 770's wins are confined to its Vulkan benchmark showing, where it recorded 19,070 points in Geekbench Vulkan, and its lower power draw. The GTX 770 also wins on the basis of its Metal score of 9,369 in Geekbench Metal, though these are not comparable directly to the RTX PRO 6000's single workload.

For users stuck with legacy PCIe 3.0 motherboards or systems lacking PCIe 5.0 support, the GTX 770's interface matches older hardware. Its dual DVI and DisplayPort 1.2 outputs may be sufficient for older monitors.

The RTX PRO 6000's positioning among its rivals is clear: it sits within 0.6% of the RTX 5090 D V2 and within 0.4% of AMD's Radeon PRO W7500, meaning its performance is tightly clustered near the top end of the database's tracked GPUs.

The Verdict

Choose the RTX PRO 6000 Blackwell for modern, compute-heavy 3D workloads. Its 3DMark Steel Nomad score of 16,408 at the 59th percentile places it among the fastest cards ever tested. The 188 RT cores and 752 tensor cores enable features the GTX 770 lacks entirely.

Pick the GTX 770 only if legacy compatibility matters more than performance. Its 57th percentile ranking among all GPUs places it mid-pack, with its 2.1% victory over the GTX 660 Ti showing it can still outperform some newer cards.

For anyone building a workstation or high-end workstation build, the RTX PRO 6000 is the clear choice based on the data. The GTX 770 launch MSRP was 399 USD, which the database records as its launch MSRP. The RTX PRO 6000 launch MSRP is 8,565 USD.
