AMD Radeon HD 7770M vs NVIDIA RTX PRO 6000D Blackwell Max-Q Comparison

# Head-to-Head Benchmarks

The benchmark database contains only a single measured score for each of these two GPUs, and they do not share a common test. The AMD Radeon HD 7770M was evaluated with Geekbench Metal, where it recorded a score of 13,536. The NVIDIA RTX PRO 6000D Blackwell Max-Q was evaluated with 3DMark Steel Nomad DX12, where it recorded a score of 11,088. Because these tests measure different workloads, a direct head-to-head comparison is not possible from the recorded data.

However, the database places each GPU within its own performance neighborhood. The Radeon HD 7770M sits at the 54th percentile among all GPUs in the database. Its nearest rivals are tightly clustered: the AMD Radeon RX 9070 XT scores 13,543, which is 0.1% higher than the HD 7770M, while the NVIDIA GeForce GTX 570 scores 13,515, just 0.2% lower. The NVIDIA P106-090 scores 13,470, 0.5% lower, and the AMD Radeon Pro 555 scores 13,407, a full 1% lower. These deltas show the HD 7770M performing essentially at parity with the RX 9070 XT and GTX 570, despite the vast generational gap. The database's nearest-rival data indicates the HD 7770M is not an outlier; it lands squarely within a normal distribution of scores around its own result.

The RTX PRO 6000D Blackwell Max-Q, by contrast, sits at the 50th percentile, with its nearest rival being itself (a 0% delta), followed by the AMD Radeon RX 550 at 11,075, which is 0.1% lower, and the NVIDIA GeForce GTX 1650 SUPER at 11,047, which is 0.4% lower. The AMD FirePro W4300 scores 11,225, which is 1.2% higher than the RTX PRO 6000D. This places the RTX PRO 6000D in a mid-pack position within its own test, though the test itself (3DMark Steel Nomad DX12) is a modern, demanding workload.

The two GPUs occupy opposite ends of the performance spectrum in terms of absolute capability, but the database's percentile scores show both are near the median of their respective test pools. The HD 7770M's 54th percentile and the RTX PRO 6000D's 50th percentile both indicate that each GPU performs as expected relative to the other entries in their benchmark cohorts.

One notable observation: the HD 7770M's score of 13,536 in Geekbench Metal is 2,448 points higher than the RTX PRO 6000D's 11,088 in 3DMark Steel Nomad DX12. This does not imply the older GPU is faster; the tests are entirely different, with Metal being a compute-oriented API test and Steel Nomad being a rasterization-heavy DX12 benchmark. The database records no shared tests for these two products, so any attempt to infer a winner would be unsupported by the data.

# Architecture Differences

The two GPUs are separated by more than a decade of silicon evolution. The AMD Radeon HD 7770M is built on the Graphics Core Next 1.0 architecture, using the Chelsea chip. It is fabricated on a 28 nm process at TSMC, with 1,500 million transistors packed into a 123 mm² die. The transistor density is 12.2 million transistors per square millimeter. This is a modest, efficient design from 2012, intended for mainstream mobile graphics.

The NVIDIA RTX PRO 6000D Blackwell Max-Q is a completely different class of hardware. It uses the Blackwell 2.0 architecture with the GB202 chip, built on a 5 nm process at TSMC. The die contains 92,200 million transistors on a 750 mm² piece of silicon, yielding a transistor density of 122.9 million transistors per square millimeter. That is roughly ten times the density of the HD 7770M, reflecting the enormous advances in process technology and design complexity.

The RTX PRO 6000D includes dedicated hardware that the HD 7770M lacks entirely: 188 ray tracing cores and 752 tensor cores. The HD 7770M has no ray tracing or tensor core support, as those features did not exist in the GCN 1.0 architecture. The RTX PRO 6000D also supports half-precision floating point (FP16) at a 1:1 ratio with FP32, whereas the HD 7770M has no recorded FP16 capability.

The memory subsystem differs fundamentally. The HD 7770M uses 1,024 MB of GDDR5 memory on a 128-bit bus, delivering 64.00 GB/s of bandwidth. The RTX PRO 6000D uses 96 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth. That is a 28-fold increase in raw bandwidth and a 96-fold increase in memory capacity.

The bus interface also reflects the generational gap. The HD 7770M uses PCIe 2.0 x16, while the RTX PRO 6000D uses PCIe 5.0 x16. The RTX PRO 6000D supports DirectX 12 Ultimate (12_2), which includes features like mesh shaders and variable rate shading, while the HD 7770M is limited to DirectX 12 (11_1). The RTX PRO 6000D also supports Vulkan 1.4, compared to Vulkan 1.2.170 on the HD 7770M.

The RTX PRO 6000D has 752 tensor cores, which enable AI-accelerated workloads such as DLSS and other neural network operations. The HD 7770M has no such hardware. Similarly, the 188 ray tracing cores on the RTX PRO 6000D enable hardware-accelerated ray tracing, a feature entirely absent from the HD 7770M.

# Where Each One Wins

The AMD Radeon HD 7770M wins in efficiency and portability. Its TDP is 32 W, which is less than one-tenth of the RTX PRO 6000D's 300 W. This makes the HD 7770M suitable for small, battery-powered devices with no external power connectors. The RTX PRO 6000D, by contrast, requires a 16-pin power connector and a 700 W suggested PSU. The HD 7770M also has no recorded slot width, implying it is a compact mobile part, while the RTX PRO 6000D is a dual-slot, 267 mm long card designed for desktop workstations.

In raw compute capability, the RTX PRO 6000D wins decisively. Its FP32 throughput of 110.1 TFLOPS is 159 times higher than the HD 7770M's 691.2 GFLOPS. The RTX PRO 6000D also has 47 times more shading units (24,064 vs. 512) and 12 times more ROPs (192 vs. 16). Its texture rate of 1,720.6 GTexel/s is roughly 80 times higher than the HD 7770M's 21.60 GTexel/s.

For memory-intensive workloads, the RTX PRO 6000D is unmatched. Its 1.79 TB/s bandwidth is 28 times higher, and its 96 GB capacity is 96 times larger. The GDDR7 memory operates at 28 Gbps effective, compared to 4 Gbps on the GDDR5 memory of the HD 7770M. The RTX PRO 6000D's 512-bit bus is four times wider than the HD 7770M's 128-bit bus.

The RTX PRO 6000D is the only one of the two with ray tracing and tensor core hardware. That makes it suitable for modern rendering workloads that rely on ray-traced effects, as well as AI inference and training tasks. The HD 7770M cannot run these workloads at all, since it lacks the dedicated hardware.

In terms of API support, the RTX PRO 6000D supports DirectX 12 Ultimate and Vulkan 1.4, which are the latest standards. The HD 7770M is limited to DirectX 12 (11_1) and Vulkan 1.2.170. Both support OpenGL 4.6.

The HD 7770M wins in the Geekbench Metal test with a score of 13,536, while the RTX PRO 6000D scores 11,088 in 3DMark Steel Nomad DX12. However, these are separate tests with different workloads, so this is not a meaningful comparison.

The production status also differentiates them. The HD 7770M is end-of-life, while the RTX PRO 6000D is active. The HD 7770M's predecessor is Vancouver and its successor is Solar System. The RTX PRO 6000D's predecessor is Workstation Ada, and no successor is recorded.

For users who need a low-power, legacy GPU for basic display or compute tasks, the HD 7770M remains a viable option. For anyone requiring high-end rendering, AI acceleration, ray tracing, or large memory capacity, the RTX PRO 6000D is the clear choice. The database does not record any shared benchmarks between the two, so the practical winner depends entirely on the workload and platform constraints.
