AMD Radeon Pro 575 vs AMD Radeon RX 7700S Comparison

Head-to-Head Benchmarks

The recorded data shows two entirely different performance profiles. In Geekbench OpenCL, the AMD Radeon RX 7700S delivers a decisive victory. Its score of 62,983 dwarfs the Radeon Pro 575's 34,596, a 45.1% deficit for the older card. That is not a marginal gap; it is a generational leap in raw compute throughput. The RX 7700S produces 20.48 TFLOPS of FP32 performance compared to 4.489 TFLOPS on the Pro 575, which explains why OpenCL workloads favor it so heavily.

The Vulkan result flips the script, though not by nearly as much. The Radeon Pro 575 scores 37,878 in Geekbench Vulkan, edging out the RX 7700S's 36,380. That is a 4.1% advantage for the Pro 575, a modest but real win. The RX 7700S supports Vulkan 1.4 while the Pro 575 only reaches Vulkan 1.3, yet the older architecture still comes out ahead in this specific test. The data suggests the Pro 575's driver maturity or memory subsystem characteristics give it an edge in Vulkan workloads, despite the RX 7700S having far higher theoretical throughput.

The RX 7700S also has a 3DMark Steel Nomad DX12 result of 2,185, a test the Pro 575 has no recorded score for. That means in any DX12-heavy scenario, the RX 7700S is the only one of the two with measured data to rely on. The Pro 575 supports DirectX 12 (12_0) while the RX 7700S supports DirectX 12 Ultimate (12_2), so the newer card has access to more modern rendering features, including hardware ray tracing.

Architecture Differences

The two cards come from completely different design eras. The Radeon Pro 575 uses the Ellesmere chip built on GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. The RX 7700S uses the Navi 33 chip with RDNA 3.0 architecture, built on a 6 nm process at TSMC. That process shrink is enormous: 14 nm versus 6 nm. The transistor counts reflect it. The Pro 575 packs 5,700 million transistors on a 232 mm² die, giving a transistor density of 24.6 million per mm². The RX 7700S crams 13,300 million transistors into a smaller 204 mm² die, achieving 65.2 million transistors per mm². Nearly three times the density on a smaller chip.

Both cards have 2,048 shading units and 128 texture mapping units, but the ROP count doubles from 32 on the Pro 575 to 64 on the RX 7700S. The RX 7700S also adds 32 ray tracing cores, something the Pro 575 lacks entirely. That is a feature gap, not just a performance gap. The Pro 575's FP16 throughput matches its FP32 at 4.489 TFLOPS (1:1 ratio), while the RX 7700S doubles its FP16 rate to 40.96 TFLOPS (2:1 ratio). The newer card has 4.6 times the FP32 throughput and over 9 times the FP16 throughput.

Memory is another generational split. The Pro 575 uses 4 GB of GDDR5 on a 256 bit bus, delivering 217.0 GB/s of bandwidth. The RX 7700S uses 8 GB of GDDR6 on a 128 bit bus, yet still achieves 288.0 GB/s thanks to much faster memory clocks: 2250 MHz with 18 Gbps effective versus 1695 MHz with 6.8 Gbps effective. The RX 7700S has half the bus width but 32.7% more bandwidth and double the capacity.

Power behavior differs sharply. The Pro 575 is rated at 150 W TDP and comes as an MXM Module, while the RX 7700S is rated at only 100 W TDP and is an IGP. The RX 7700S delivers dramatically higher performance at two-thirds the power draw. Bus interface also advances from PCIe 3.0 x16 to PCIe 4.0 x16. The RX 7700S is actively in production while the Pro 575 is end-of-life, released in June 2017 versus January 2023.

The Verdict

The data points to a clear overall winner for anyone needing raw compute performance: the AMD Radeon RX 7700S. It wins the OpenCL benchmark by 45.1%, has 4.6 times the FP32 throughput, double the memory capacity, higher bandwidth, ray tracing support, and does all of that at 100 W TDP versus 150 W. Its average benchmark score of 33,849 places it in the 78th percentile of all GPUs, and its nearest rivals include the NVIDIA RTX A5000 with a 0.7% delta, meaning it sits in respectable company.

The Radeon Pro 575 is not without merit. Its average benchmark score of 39,555 puts it in the 82nd percentile, higher than the RX 7700S's 78th percentile. Its nearest rival is the NVIDIA RTX A500 Mobile at a 0% delta, and it beats the AMD Radeon Pro WX 7100 by 1.3%. The Vulkan win over the RX 7700S is notable, and its 256 bit memory bus provides 217.0 GB/s of bandwidth from a design that was competitive in its era. But the Pro 575 is end-of-life, uses a 14 nm process, lacks ray tracing, and has a 45.1% OpenCL deficit. The RX 7700S is the better card for modern workloads, with the Vulkan result being the only significant counterpoint in the Pro 575's favor.

Where Each One Wins

Pick the AMD Radeon RX 7700S for compute-heavy tasks. OpenCL workloads show a 45.1% advantage, and the raw numbers back it up: 20.48 TFLOPS FP32, 40.96 TFLOPS FP16, 64 ROPs, and 32 ray tracing cores. The 8 GB GDDR6 memory with 288.0 GB/s bandwidth gives it double the capacity and 32.7% more bandwidth than the Pro 575. Its 100 W TDP makes it far more efficient for laptops, and PCIe 4.0 x16 doubles the bus bandwidth available to it. It is also the only one of the two with a recorded DX12 benchmark score, 2,185 in 3DMark Steel Nomad, making it the safer choice for modern gaming and DX12 Ultimate titles.

Pick the AMD Radeon Pro 575 for Vulkan-specific workloads and legacy compatibility. It wins Geekbench Vulkan by 4.1%, which suggests its driver stack and memory architecture handle Vulkan tasks well despite the older silicon. Its 256 bit memory bus provides 217.0 GB/s of bandwidth, and its 82nd percentile ranking versus 78th for the RX 7700S shows it still competes respectably in aggregate benchmarks. It also supports OpenGL 4.6 and DirectX 12 (12_0), which covers older applications. For someone running Vulkan-based professional software, the single benchmark win may matter more than the sweeping compute advantages of the RX 7700S. For everything else, the RX 7700S is the data-backed choice.
