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

Head-to-Head Benchmarks

The database contains no directly comparable benchmark runs between the AMD Radeon HD 7770M and the NVIDIA RTX PRO 6000 Blackwell Max-Q. The two GPUs were measured in entirely different test suites, so a direct per-test comparison is not possible. The AMD Radeon HD 7770M records a single GeekBench Metal score of 13,536, placing it at the 54th percentile of all GPUs in the database. The NVIDIA RTX PRO 6000 Blackwell Max-Q, meanwhile, delivers a 3DMark Steel Nomad DX12 score of 11,088, which puts it at the 50th percentile. These are different workloads measuring different capabilities, and the raw numbers cannot be subtracted or divided to produce a meaningful head-to-head performance ratio.

Instead, the useful comparison comes from each card's position relative to its own nearest rivals. The AMD part sits within a tight cluster: the AMD Radeon RX 9070 XT scores 13,543, just 0.1% higher, which is effectively a statistical tie. The NVIDIA GeForce GTX 570 scores 13,515, 0.2% lower, and the NVIDIA P106-090 scores 13,470, 0.5% lower. The AMD Radeon Pro 555 trails by 1% at 13,407. This grouping shows the HD 7770M performing at parity with much newer and larger discrete cards in this particular Metal benchmark, despite its age and low power envelope. The 54th percentile ranking confirms it sits slightly above the median of all recorded GPUs.

The NVIDIA RTX PRO 6000 Blackwell Max-Q, in contrast, finds itself in an unusual neighborhood for a workstation flagship. Its 3DMark Steel Nomad DX12 score of 11,088 is exactly matched by the NVIDIA RTX PRO 6000D Blackwell Max-Q, with a 0% delta. The AMD Radeon RX 550 scores 11,075, only 0.1% behind, and the NVIDIA GeForce GTX 1650 SUPER scores 11,047, 0.4% behind. The AMD FirePro W4300 is the only rival that beats it, scoring 11,225, which is 1.2% higher. This clustering is striking: a 300 W professional GPU with 96 GB of GDDR7 memory sits within 1.2% of entry-level consumer cards in this specific DirectX 12 benchmark. The 50th percentile ranking reflects that middling position.

The takeaway is that neither GPU shows a dominant lead over the other in the recorded data, because the data does not link them directly. What the numbers do show is that each card performs at the center of its own competitive set. The HD 7770M is a 2012-era mobile part that holds its own against much newer silicon in Metal compute. The RTX PRO 6000 Blackwell Max-Q is a current-generation workstation card that, in this particular DX12 test, does not separate itself from low-end desktop parts. The recorded scores tell a story of context: benchmark selection matters enormously, and a single test can place a flagship and an entry card in the same percentile band.

Where Each One Wins

The AMD Radeon HD 7770M wins in the Metal compute workload. Its GeekBench Metal score of 13,536 beats all four of its nearest rivals, with the closest competitor only 0.1% ahead and the furthest 1% behind. This suggests strong compute throughput in Apple's Metal API for a GPU with only 512 shading units and 32 texture mapping units. The card also wins on efficiency in a relative sense: its 32 W TDP is dramatically lower than the NVIDIA part's 300 W TDP, though the database does not include a power-normalized performance metric. For any use case that relies on Metal, such as Mac-compatible workloads or OpenCL-style compute, the data shows this older AMD part performing at a competitive level.

The NVIDIA RTX PRO 6000 Blackwell Max-Q wins in raw feature support and memory capacity. It offers 96 GB of GDDR7 memory across a 512-bit bus, delivering 1.79 TB/s of bandwidth. That is an enormous memory subsystem compared to the HD 7770M's 1024 MB of GDDR5 on a 128-bit bus with 64.00 GB/s. For large datasets, AI inference, or rendering scenes that exceed 1 GB of VRAM, the NVIDIA card is the only viable option. The RTX PRO 6000 also brings dedicated hardware the AMD part lacks entirely: 188 ray tracing cores and 752 tensor cores. The HD 7770M has no such units. The NVIDIA card supports DirectX 12 Ultimate (12_2), while the AMD part tops out at DirectX 12 (11_1). Vulkan support also differs, with the NVIDIA card at version 1.4 versus the AMD card's 1.2.170.

In compute throughput, the NVIDIA part is overwhelmingly ahead. It delivers 109.7 TFLOPS of FP32 performance and 109.7 TFLOPS of FP16 (1:1), compared to the HD 7770M's 691.2 GFLOPS of FP32. That is a difference of roughly 159 times in raw floating-point throughput. The pixel rate tells a similar story: 437.8 GPixel/s versus 10.80 GPixel/s, and the texture rate is 1,714.6 GTexel/s versus 21.60 GTexel/s. For any workload that scales with shader count, the NVIDIA card wins by orders of magnitude. The HD 7770M's only wins are in the single Metal benchmark and in power draw, where it consumes 32 W versus 300 W.

Architecture Differences

The AMD Radeon HD 7770M is built on the GCN 1.0 architecture, using the Chelsea chip on a 28 nm process at TSMC. It contains 1,500 million transistors on a 123 mm² die, giving a transistor density of 12.2M per mm². It belongs to the London (HD 7700M) generation and its predecessor is Vancouver, with a successor named Solar System. Its API support includes DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170.

The NVIDIA RTX PRO 6000 Blackwell Max-Q is built on the Blackwell 2.0 architecture, using the GB202 chip on a 5 nm process at TSMC. It contains 92,200 million transistors on a 750 mm² die, giving a transistor density of 122.9M per mm². It belongs to the Blackwell PRO W (x000) generation and its predecessor is Workstation Ada. Its API support includes DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The architectural gap is immense. The NVIDIA chip has roughly 61 times more transistors on a die that is about 6 times larger, with a transistor density about 10 times higher. The AMD card has no ray tracing or tensor cores, while the NVIDIA card has 188 RT cores and 752 tensor cores. The NVIDIA card's FP16 throughput matches its FP32 throughput at a 1:1 ratio, indicating unified compute paths. The AMD card lists no FP16 capability. The process node difference, 28 nm versus 5 nm, explains much of the density and efficiency gap, though the NVIDIA card still consumes nearly 10 times the power.

The Verdict

The data supports a clear split based on workload. For anyone relying on Metal compute, the AMD Radeon HD 7770M delivers a score of 13,536 that places it at the 54th percentile, within 0.1% of the AMD Radeon RX 9070 XT and ahead of three other rivals. It does so at 32 W, which is a fraction of the NVIDIA card's 300 W draw. This makes it a sensible choice for lightweight, power-constrained systems where Metal performance is the priority and modern features are not required.

For virtually everything else, the NVIDIA RTX PRO 6000 Blackwell Max-Q is the only defensible option. Its 96 GB of GDDR7 memory, 1.79 TB/s bandwidth, 109.7 TFLOPS FP32, 188 ray tracing cores, and 752 tensor cores place it in a different performance class entirely. The 3DMark Steel Nomad score of 11,088 is modest relative to its nearest rivals, but the specification sheet shows capabilities the AMD card cannot approach in any way. The 50th percentile ranking in that one test does not reflect the card's broader utility for professional workloads. The AMD card is end-of-life, while the NVIDIA card is active and current. Users needing modern API support, ray tracing, tensor acceleration, or large memory pools should choose the NVIDIA part. Users prioritizing Metal compute efficiency in a legacy mobile platform may still find the AMD part adequate, based purely on its recorded benchmark position.
