AMD Radeon HD 6770 vs NVIDIA Quadro P1000 Comparison

NVIDIA Quadro P1000 and AMD Radeon HD 6770 represent two very different generations of graphics hardware, separated by roughly six years of architectural evolution. The data shows a single head-to-head benchmark result, but the underlying specifications and broader benchmark suites reveal distinct strengths. The Quadro P1000, built on the 14 nm Pascal architecture, dominates in absolute performance and modern feature support, while the HD 6770, a 40 nm TeraScale 2 part, holds its own in percentile ranking despite its age. This analysis breaks down where each card excels, how they compare in raw numbers, and which user should consider which, based strictly on the provided facts.

Where Each One Wins

The NVIDIA Quadro P1000 wins the only direct comparison available: the Geekbench OpenCL test, scoring 13,584 against the AMD Radeon HD 6770’s 3,649. That is a 272.3% delta, meaning the Quadro delivers more than 3.7 times the compute throughput in this specific workload. This is not a marginal victory; it is a generational gap made visible by raw compute resources. The Quadro’s FP32 performance is listed at 1.894 TFLOPS, while the HD 6770 manages 1,360.0 GFLOPS (1.36 TFLOPS), so the OpenCL result tracks closely with theoretical peak, though the Quadro’s lead is larger in practice than those raw numbers would suggest.

Beyond that single head-to-head, the Quadro P1000 has a full benchmark suite to examine. Its Passmark G3D score is 4,512, and its Passmark G2D score is 589, with a Passmark GPU Compute score of 1,891. The HD 6770 has no such results in the data, so its strengths must be inferred from its percentile and average score. The HD 6770 holds a 22nd percentile ranking among all GPUs, slightly better than the Quadro’s 20th percentile. Its average benchmark score of 3,649 is higher than the Quadro’s average of 3,163, which is the only metric where the older card comes out ahead. That average is skewed by the fact that the HD 6770 has only one benchmark result, while the Quadro has nine, including several legacy DirectX tests where scores are very low (e.g., 21 in Passmark DirectX 10, 19 in DirectX 12).

Where the HD 6770 wins is in relative positioning against its own peers. Its nearest rival, the NVIDIA GeForce GTX 1050, scores 3,629, a delta of only 0.6%, meaning the HD 6770 is effectively tied with that much newer card in average score. The Quadro P1000, by contrast, trails its closest rival, the Intel Arc Pro B60, by 0.6%, and is 1.5% behind the NVIDIA GeForce GT 640. So the HD 6770 punches above its weight in aggregate comparisons, while the Quadro is slightly below expectations for its class.

The Verdict

Pick the NVIDIA Quadro P1000 if you need compute performance, modern API support, or efficiency. The data is unambiguous: it wins the only head-to-head benchmark by 272.3%, offers 4 GB of GDDR5 memory versus 1 GB, and supports DirectX 12 (12_1) and Vulkan 1.4, whereas the HD 6770 tops out at DirectX 11.2 and has no Vulkan support. The Quadro also uses far less power (47 W TDP versus 108 W), is single-slot versus dual-slot, and requires no external power connectors, making it the clear choice for any system where thermals or space are constraints.

Pick the AMD Radeon HD 6770 only if you are limited to legacy software or need a card that scores well in aggregate benchmarks relative to its release era. Its 22nd percentile ranking is above the Quadro’s 20th, and its average score of 3,649 beats the Quadro’s 3,163. But that advantage is entirely an artifact of the HD 6770 having a single OpenCL result, which is 3,649 — a number the Quadro exceeds by nearly four times in the same test. For any modern workload, the Quadro is the objectively stronger part. The HD 6770’s only real claim is historical: it was competitive in its day, costing 129 USD at launch, but that price is not a recommendation for current use.

Head-to-Head Benchmarks

The sole direct comparison in the data is Geekbench OpenCL, and it is a decisive win for the NVIDIA Quadro P1000. The Quadro scores 13,584, while the AMD Radeon HD 6770 scores 3,649. The delta is 272.3%, meaning the Quadro is more than 3.7 times faster in this compute-oriented test. This aligns with the theoretical FP32 numbers: the Quadro’s 1.894 TFLOPS is roughly 39% higher than the HD 6770’s 1,360.0 GFLOPS, but the actual benchmark shows a much larger gap, suggesting architectural efficiency differences beyond raw throughput.

The HD 6770 has no other benchmark results, so this single data point is the only direct evidence of performance. The Quadro’s other scores — Passmark G3D at 4,512, Passmark G2D at 589, and Passmark GPU Compute at 1,891 — cannot be compared head-to-head because the HD 6770 lacks those entries. However, the Quadro’s Passmark DirectX 9 score of 79, DirectX 11 score of 31, and DirectX 10 score of 21 show that its legacy API performance is weak, which is unsurprising given its Pascal architecture is designed for modern workloads. If the HD 6770 had been tested on those same legacy paths, its TeraScale 2 architecture might have fared better, but that is speculation; the data does not provide those numbers.

Architecture Differences

The NVIDIA Quadro P1000 is built on the Pascal architecture using the GP107 chip, manufactured on a 14 nm process at Samsung. It contains 3,300 million transistors on a 132 mm² die, yielding a transistor density of 25.0M per mm². The AMD Radeon HD 6770 uses the TeraScale 2 architecture with the Juniper chip, fabricated on a 40 nm process at TSMC. It has 1,040 million transistors on a larger 166 mm² die, giving a much lower density of 6.3M per mm². The process node difference is the primary driver of efficiency: the Quadro packs more than three times the transistors into a smaller area.

The Quadro’s compute resources are configured as 640 shading units, 40 texture mapping units, and 32 ROPs. The HD 6770 has 800 shading units, 40 TMUs, but only 16 ROPs. Despite fewer shaders, the Quadro achieves higher pixel and texture rates: 47.36 GPixel/s and 59.20 GTexel/s, versus 13.60 GPixel/s and 34.00 GTexel/s for the HD 6770. The Quadro also supports FP16 at 29.60 GFLOPS (1:64 ratio), while the HD 6770 has no FP16 data. Neither card has ray tracing or tensor cores, so those features are absent from both.

The Quadro’s memory runs at 1253 MHz (5 Gbps effective), delivering 80.19 GB/s across a 128-bit bus. The HD 6770’s memory is clocked at 1200 MHz (4.8 Gbps effective), providing 76.80 GB/s on the same bus width. The Quadro’s bus interface is PCIe 3.0 x16, while the HD 6770 uses the older PCIe 2.0 x16. Display outputs also differ: the Quadro has four mini-DisplayPort 1.4a connections, while the HD 6770 offers two DVI, one HDMI 1.3a, and two mini-DisplayPort 1.1 ports.

The Quadro P1000 is shorter, cooler, and more power-efficient, while the HD 6770 is longer, hotter, and requires more system power. The Quadro’s base clock of 1266 MHz and boost of 1480 MHz give it a significant frequency advantage, as the HD 6770 has no listed base or boost clocks. The HD 6770’s only numeric advantages are its higher shading unit count (800 versus 640) and its higher percentile ranking (22 versus 20). Everything else favors the Quadro, from memory capacity to API support to physical dimensions.
