AMD Radeon PRO W7600 vs NVIDIA RTX 4500 Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data shows a dominant performance gap between the NVIDIA RTX 4500 Ada Generation and the AMD Radeon PRO W7600. In the Geekbench OpenCL test, the NVIDIA card scores 160,786, while the AMD card manages 81,528. That is a delta of 97.2%, meaning the RTX 4500 Ada is nearly twice as fast in this compute workload. The margin is slightly narrower in the Vulkan test, but still decisive: NVIDIA scores 171,401 against AMD's 92,688, a difference of 84.9%. Across the two recorded benchmark tests, the NVIDIA card wins both, giving it a clean 2-0 record.

The NVIDIA card's average benchmark score of 166,094 places it in the 97th percentile of all GPUs in the database. Its nearest rivals include the AMD Radeon PRO W7800, which trails by just 0.7%, and the NVIDIA RTX A5500, which is 0.5% behind. The AMD Radeon Pro W6900X sits ahead by 1.5%, while the NVIDIA A100 PCIe 40 GB is 2.2% behind. The RTX 4500 Ada is clearly positioned at the top end of workstation-class performance, with only a handful of cards edging it out.

The AMD Radeon PRO W7600, by contrast, averages 87,108 in recorded benchmarks, placing it in the 93rd percentile. Its nearest rivals are a mixed bag: the NVIDIA Quadro GP100 is just 0.4% ahead, and the NVIDIA CMP 40HX is 1.7% behind. The NVIDIA RTX A4500 Mobile leads it by 4.4%, and the desktop NVIDIA RTX A4500 is 5% ahead. The W7600 is therefore a mid-range workstation card, competitive with older or mobile parts, but nowhere near the absolute top tier that the RTX 4500 Ada occupies.

Looking at the raw numbers, the NVIDIA card's 39.63 TFLOPS of FP32 compute is exactly double the AMD card's 19.99 TFLOPS. That aligns with the 97.2% OpenCL delta, which is nearly a perfect 2x scaling. The Vulkan result shows a slightly smaller gap, suggesting the AMD architecture closes some distance in graphics-oriented APIs, but the NVIDIA card still holds a commanding lead.

Where Each One Wins

The NVIDIA RTX 4500 Ada Generation wins decisively in both recorded benchmark categories, so the use-case split is straightforward. For OpenCL compute tasks, such as rendering, physics simulation, or data processing, the NVIDIA card delivers 97.2% higher performance. This is the kind of workload where the Ada card's 7,680 shading units, 240 texture units, and 60 RT cores come into play. The FP32 throughput of 39.63 TFLOPS is a strong indicator for raw compute density.

In Vulkan workloads, which are more common in real-time graphics and game development, the NVIDIA card again wins, this time by 84.9%. The margin is still huge, but the slight reduction from the OpenCL gap suggests that AMD's RDNA 3.0 architecture handles draw calls and graphics pipelines relatively better than its compute throughput. Still, the RTX 4500 Ada's 171,401 Vulkan score is among the highest recorded in the database, so it remains the preferred choice for any graphics-heavy professional task.

The AMD Radeon PRO W7600 has no benchmark wins in this comparison. Its strengths lie elsewhere, specifically in power efficiency and physical footprint. With a TDP of 130 W compared to the NVIDIA card's 210 W, the AMD card draws significantly less power. It is also a single-slot card, while the NVIDIA card is dual-slot, making the W7600 a better fit for dense multi-GPU systems or compact chassis where space and cooling are limited. For users who prioritize low power draw and a smaller physical profile over peak performance, the W7600 has a clear role.

Architecture Differences

The two cards come from fundamentally different architectural lineages. The NVIDIA RTX 4500 Ada Generation is built on the Ada Lovelace architecture, using the AD103 chip. It is fabricated on a 5 nm process at TSMC, with 45,900 million transistors packed into a 379 mm² die. This yields a transistor density of 121.1M per mm², which is exceptionally high and reflects the advanced process node. The architecture supports 60 RT cores and 240 tensor cores, giving it dedicated hardware for ray tracing and AI acceleration.

The AMD Radeon PRO W7600 uses the RDNA 3.0 architecture, based on the Navi 33 chip, codenamed "Hotpink Bonefish." It is built on a 6 nm process at TSMC, with 13,300 million transistors on a 204 mm² die. The transistor density is 65.2M per mm², roughly half that of the NVIDIA chip. The W7600 has 32 RT cores, but no tensor cores, so it lacks dedicated AI acceleration hardware. Its FP16 throughput is 39.98 TFLOPS at a 2:1 rate relative to FP32, whereas the NVIDIA card achieves 39.63 TFLOPS at a 1:1 ratio, meaning the Ada card does not sacrifice FP16 performance.

The memory subsystem also differs significantly. The NVIDIA card uses a 192-bit bus with 24 GB of GDDR6 memory, delivering 432.0 GB/s of bandwidth. The AMD card uses a narrower 128-bit bus with 8 GB of GDDR6 memory, resulting in 288.0 GB/s. The NVIDIA card's larger memory capacity and higher bandwidth are critical for large datasets and high-resolution textures, while the AMD card's smaller pool may limit it in memory-intensive applications.

Specification Differences

The two cards differ in nearly every measurable specification. The NVIDIA RTX 4500 Ada Generation has a base clock of 2070 MHz and a boost clock of 2580 MHz, while the AMD Radeon PRO W7600 operates at 1720 MHz base and 2440 MHz boost. The NVIDIA card has 7,680 shading units, 240 TMUs, and 80 ROPs, compared to the AMD card's 2,048 shading units, 128 TMUs, and 64 ROPs. The pixel rate is 206.4 GPixel/s for NVIDIA versus 156.2 GPixel/s for AMD, and the texture rate is 619.2 GTexel/s versus 312.3 GTexel/s.

Memory capacity is a major differentiator: 24 GB on the NVIDIA card versus 8 GB on the AMD card. The bus width is 192-bit versus 128-bit, and bandwidth is 432.0 GB/s versus 288.0 GB/s. The NVIDIA card has a TDP of 210 W and requires a 550 W suggested PSU, while the AMD card has a TDP of 130 W and a 300 W suggested PSU. The NVIDIA card is dual-slot with no power connectors (using the PCIe slot for power), while the AMD card is single-slot with a single 6-pin connector.

The bus interface also differs: the NVIDIA card uses PCIe 4.0 x16, while the AMD card uses PCIe 4.0 x8. Display outputs are 4x DisplayPort 1.4a on the NVIDIA card versus 4x DisplayPort 2.1 on the AMD card, meaning the AMD card supports a newer display standard. The NVIDIA card measures 245 mm in length and 112 mm in height, while the AMD card is 241 mm long and 115 mm tall, making them nearly identical in physical size despite the slot width difference. The NVIDIA card was released on August 8, 2023, while the AMD card came out on August 2, 2023, just six days earlier.
