AMD Radeon RX 7700S vs NVIDIA RTX PRO 4500 Blackwell Comparison

The AMD Radeon RX 7700S and the NVIDIA RTX PRO 4500 Blackwell occupy vastly different corners of the GPU landscape, as the benchmark data makes immediately clear. The RX 7700S is a mobile-first RDNA 3 part aimed at high-performance laptops, while the RTX PRO 4500 is a desktop workstation behemoth built on the latest Blackwell architecture. Across the two shared benchmark tests, the NVIDIA card dominates decisively, but the AMD part holds its own as a more efficient, compact alternative. The data shows a clear stratification in performance, memory capacity, and physical design, making the choice between them straightforward for most users.

Head-to-Head Benchmarks

The benchmark results paint a one-sided picture in favor of the NVIDIA RTX PRO 4500 Blackwell. In the demanding 3DMark Steel Nomad DX12 test, the NVIDIA card scores 7,025 points against the AMD Radeon RX 7700S’s 2,185 points. This represents a massive 68.9% performance deficit for the AMD part, meaning the RTX PRO 4500 delivers more than triple the frame throughput in this modern, API-heavy workload. The gulf is even wider in the Geekbench Vulkan test, where the NVIDIA card posts 221,768 points versus 36,380 for the RX 7700S, an 83.6% gap. This suggests that the RTX PRO 4500’s architecture scales far better with low-level, multi-threaded compute tasks, likely due to its vastly higher shader count and memory bandwidth.

The RX 7700S does not win either of the shared benchmarks, but its performance profile is not without merit. Its average benchmark score across all tests stands at 33,849, which places it in the 78th percentile of all GPUs. That is actually a higher percentile ranking than the RTX PRO 4500’s 76th percentile, despite the NVIDIA card’s higher raw scores in the head-to-head tests. The reason is that the RTX PRO 4500’s average score of 31,532 is dragged down by its anomalous PassMark DirectX results, which include scores as low as 119 in the DX12 test and 204 in the DX10 test. These low scores are likely artifacts of the workstation card’s driver optimization for compute over legacy rasterization, but they affect its overall average. Meanwhile, the RX 7700S’s nearest rivals in the database—such as the AMD Radeon HD 7950 and RX 480, and the NVIDIA GTX 1060 5 GB—sit within a 0.5% delta of its average score, indicating that its performance is solidly mainstream.

For the RTX PRO 4500, its nearest rivals include the NVIDIA TITAN RTX (0.5% behind) and the NVIDIA Quadro M5000 (1% behind), which shows that its average score sits in a similar performance tier as those older flagship cards. The head-to-head results, however, are unambiguous: the RTX PRO 4500 wins both tests with overwhelming margins. The 3DMark delta of -68.9% and the Geekbench delta of -83.6% are not close calls; they represent completely different performance classes. The RX 7700S is competitive with mid-range desktop GPUs from several generations ago, while the RTX PRO 4500 is in a league with high-end workstation parts, even if its average score is muddied by those PassMark outliers.

Architecture Differences

The architectural gap between these two GPUs is generational and fundamental. The AMD Radeon RX 7700S is built on the RDNA 3.0 architecture, fabricated on a 6 nm process at TSMC, with the chip codenamed “Hotpink Bonefish” and part of the Navi Mobile generation. This is a mobile-first design with a die size of 204 mm² and 13,300 million transistors, yielding a transistor density of 65.2 million per mm². In contrast, the NVIDIA RTX PRO 4500 Blackwell uses the Blackwell 2.0 architecture on a more advanced 5 nm TSMC process, with the GB203 chip. Its die is significantly larger at 378 mm² and packs 45,600 million transistors, achieving a density of 120.6 million per mm²—nearly double that of the AMD part.

The core configurations diverge sharply. The RX 7700S has 2,048 shading units, 128 texture mapping units, 64 ROPs, and 32 ray tracing cores. The RTX PRO 4500, meanwhile, equips 10,496 shading units, 328 TMUs, 112 ROPs, and 82 RT cores, along with 328 tensor cores that the AMD card lacks entirely. This 5x difference in shading units and 2.5x difference in RT cores explains the performance chasm in compute-heavy tests. The NVIDIA card also has a higher base clock of 1,635 MHz versus 1,500 MHz, though the AMD part has a slightly higher boost clock at 2,500 MHz versus 2,407 MHz, and a game clock of 2,200 MHz that the NVIDIA card does not list. The AMD card’s FP32 throughput is 20.48 TFLOPS, while the NVIDIA card achieves 50.53 TFLOPS at both FP32 and FP16, indicating a 1:1 ratio versus the AMD card’s 2:1 FP16 ratio.

Memory architecture is another major differentiator. The RX 7700S features 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The RTX PRO 4500 offers 32 GB of GDDR7 on a 256-bit bus, with 896.0 GB/s of bandwidth—over three times the capacity and bandwidth. This makes the NVIDIA card vastly more capable for large dataset workloads, such as AI inference or high-resolution rendering. The AMD card’s power envelope is also far lower at 100 W TDP versus the NVIDIA card’s 200 W TDP, but the latter requires a single 16-pin power connector and a 550 W suggested PSU, while the RX 7700S is an IGP with no power connectors, designed for portable devices.

Specification Differences

The two GPUs differ in nearly every measurable specification. The process node is 6 nm for AMD versus 5 nm for NVIDIA, with transistor counts of 13,300 million and 45,600 million, respectively. Die size is 204 mm² for the RX 7700S and 378 mm² for the RTX PRO 4500, leading to transistor densities of 65.2M / mm² and 120.6M / mm². Clock speeds vary: the AMD card boosts to 2,500 MHz and has a game clock of 2,200 MHz, while the NVIDIA card boosts to 2,407 MHz with no game clock listed. Memory is 8 GB GDDR6 with 288.0 GB/s bandwidth for AMD, versus 32 GB GDDR7 with 896.0 GB/s for NVIDIA.

The core counts are starkly different: 2,048 shading units, 128 TMUs, 64 ROPs, and 32 RT cores for AMD, versus 10,496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores for NVIDIA. Pixel and texture rates follow suit, with AMD at 160.0 GPixel/s and 320.0 GTexel/s, while NVIDIA reaches 269.6 GPixel/s and 789.5 GTexel/s. FP32 performance is 20.48 TFLOPS for AMD and 50.53 TFLOPS for NVIDIA, with FP16 at 40.96 TFLOPS (2:1) for AMD and 50.53 TFLOPS (1:1) for NVIDIA. Power consumption is 100 W versus 200 W, and physical design differs: the RX 7700S is an IGP with no power connectors, while the RTX PRO 4500 is a dual-slot card measuring 267 mm in length, 111 mm in height, and 40 mm in width, with a 16-pin connector. The bus interface is PCIe 4.0 x16 for AMD and PCIe 5.0 x16 for NVIDIA, and display outputs are portable-device-dependent for AMD versus 4x DisplayPort 2.1b for NVIDIA.

The Verdict

The data dictates a clear verdict based on use case. The NVIDIA RTX PRO 4500 Blackwell is the unequivocal choice for any workload requiring maximum compute throughput, large memory capacity, or professional rendering. Its 32 GB of GDDR7 memory and 896.0 GB/s bandwidth are essential for tasks like 3D scene compositing, AI model training, or handling massive textures, and its 50.53 TFLOPS FP32 performance is over 2.4x that of the RX 7700S. The 83.6% lead in Geekbench Vulkan and 68.9% lead in 3DMark Steel Nomad are decisive, making it the superior option for any user who needs raw speed and does not mind the 200 W TDP, dual-slot footprint, and external power requirement.

The AMD Radeon RX 7700S, by contrast, is the right pick for portable or power-constrained systems. Its 100 W TDP and IGP form factor require no power connectors, making it suitable for thin-and-light laptops where the RTX PRO 4500’s 267 mm length and dual-slot design would be impossible. Its 78th percentile ranking and average score of 33,849, which is actually higher than the RTX PRO 4500’s average, show that it is no slouch for mainstream gaming and general GPU tasks. Users who need 8 GB of memory or less, and who prioritize mobility over peak performance, will find the RX 7700S adequate. However, for anyone building a desktop workstation with space and power headroom, the RTX PRO 4500’s benchmark results make it the only rational choice, provided the workload justifies its 32 GB frame buffer and higher compute ceiling. The RX 7700S wins on efficiency and portability, but the RTX PRO 4500 wins on every measurable performance metric in the shared tests.
