AMD Radeon Pro 555 vs NVIDIA GeForce GTX 1070 Ti Comparison

The NVIDIA GeForce GTX 1070 Ti and the AMD Radeon Pro 555 occupy opposite ends of the GPU spectrum, yet both are end-of-life products. The GeForce part is a desktop-class Pascal chip with a 180 W TDP, while the Radeon Pro is a 75 W integrated-class mobile part based on GCN 4.0. Benchmark data shows a decisive performance gap across all shared tests, but the Radeon’s role as a low-power, portable-device component means raw speed is not its primary objective. The analysis below uses only the provided benchmark scores and specifications to compare these two architectures.

FAQ

Q: Which GPU has the higher average benchmark score?

A: The NVIDIA GeForce GTX 1070 Ti scores 14,277 on average, while the AMD Radeon Pro 555 scores 13,407. The GeForce leads by 870 points, a 6.5% advantage in aggregate performance.

Q: How large is the performance gap in the Geekbench OpenCL test?

A: The GTX 1070 Ti scores 49,219, versus 11,682 for the Radeon Pro 555. This is a delta of 321.3%, meaning the NVIDIA part delivers more than four times the OpenCL compute performance.

Q: Does the Radeon Pro 555 win any direct comparison?

A: No. In the three head-to-head benchmarks (Geekbench Metal, OpenCL, and Vulkan), the NVIDIA card wins all three. The win count is 3 for the GTX 1070 Ti and 0 for the Radeon Pro 555.

Q: What is the transistor density difference between the two chips?

A: The AMD Polaris 21 has a density of 24.4M transistors per mm², which is slightly higher than the NVIDIA GP104’s 22.9M / mm². However, the GP104 packs 7,200 million transistors on a 314 mm² die, versus 3,000 million on 123 mm² for the Polaris 21.

Q: How do their percentile rankings compare among all GPUs?

A: The GTX 1070 Ti sits at the 56th percentile, while the Radeon Pro 555 is at the 54th percentile. Despite the large score differences in specific tests, both parts cluster near the middle of the database.

Q: What are the nearest rivals for each card based on average score?

A: For the GTX 1070 Ti, the closest rival is the Intel Iris Xe MAX Graphics, which is 0.3% slower. For the Radeon Pro 555, the AMD Radeon HD 8950M is 0.2% faster, and the AMD Radeon RX 5500M is 0.4% faster.

The Verdict

For any workload where compute throughput or 3D rendering is the priority, the NVIDIA GeForce GTX 1070 Ti is the clear choice. The data shows it outperforms the Radeon Pro 555 by 36.6% in Geekbench Metal, 321.3% in OpenCL, and 395.9% in Vulkan. The GeForce also has 8 GB of GDDR5 memory on a 256-bit bus, yielding 256.3 GB/s of bandwidth, compared to the Radeon’s 2 GB on a 128-bit bus at 81.60 GB/s. This makes the GTX 1070 Ti suitable for high-resolution textures and memory-intensive workloads.

The AMD Radeon Pro 555, however, is a different class of product. It is an IGP (integrated graphics processor) with a 75 W TDP and no power connectors, meaning it is designed for portable devices where power draw and physical space are constrained. Its 1,305.6 GFLOPS FP32 performance is only about 16% of the GTX 1070 Ti’s 8.186 TFLOPS. Users who need a discrete GPU in a thin laptop might prefer the Radeon for its low power profile, but they should expect roughly one-third to one-quarter of the NVIDIA card’s performance in graphics APIs.

The Verdict hinges on context. If you are building a desktop with a 450 W power supply and want maximum benchmark scores, the GTX 1070 Ti wins every category. If you are evaluating a mobile workstation where the GPU must run on 75 W without auxiliary power, the Radeon Pro 555 is the only viable option of the two. The GeForce’s launch MSRP was 399 USD; the Radeon has no listed launch MSRP.

Head-to-Head Benchmarks

The three shared benchmarks all favor the NVIDIA GeForce GTX 1070 Ti, but the margins vary dramatically by API. In Geekbench Metal, the GTX 1070 Ti scores 22,180 against 16,236 for the Radeon Pro 555. That 36.6% lead is significant, but it is the smallest of the three deltas. Metal is Apple’s graphics API, and the Radeon Pro 555 is part of the Radeon Pro Mac 500 Series, so its relative strength here suggests some optimization for that environment.

The Geekbench OpenCL test shows a far wider gap. The GTX 1070 Ti posts 49,219, while the Radeon Pro 555 manages 11,682. The 321.3% delta indicates that the NVIDIA card’s 2,432 shading units and 152 TMUs overwhelm the Radeon’s 768 shaders and 48 TMUs. OpenCL compute workloads are heavily parallel, and the GTX 1070 Ti’s raw throughput advantage becomes obvious. The Radeon’s FP16 performance is equal to its FP32 at 1,305.6 GFLOPS (1:1 ratio), but the GTX 1070 Ti’s FP16 is a mere 127.9 GFLOPS (1:64), so the NVIDIA part relies entirely on FP32 for compute.

The largest delta appears in Geekbench Vulkan, where the GTX 1070 Ti scores 61,006 versus 12,303 for the Radeon Pro 555. That is a 395.9% difference, meaning the NVIDIA card is nearly five times faster. Vulkan is a low-overhead API, and the GTX 1070 Ti’s higher memory bandwidth (256.3 GB/s vs. 81.60 GB/s) and larger L2 cache likely contribute to this extreme result. The Radeon’s Vulkan support is version 1.3, while the NVIDIA card supports Vulkan 1.4, which may also affect performance in this test.

Overall, the GTX 1070 Ti wins 3 benchmarks to 0. The average delta across all three tests is roughly 251%, but the spread from 36.6% to 395.9% shows that the performance gap is not uniform. In API-specific workloads, the NVIDIA architecture scales better with additional hardware resources.

Specification Differences

The most obvious difference is memory configuration. The GTX 1070 Ti has 8 GB of GDDR5, while the Radeon Pro 555 has 2 GB. Bus width follows suit: 256-bit versus 128-bit, resulting in bandwidth of 256.3 GB/s compared to 81.60 GB/s. Memory clock also differs, with the NVIDIA card at 2002 MHz (8 Gbps effective) and the AMD at 1275 MHz (5.1 Gbps effective).

Core counts are vastly different. The GTX 1070 Ti has 2,432 shading units, 152 TMUs, and 64 ROPs. The Radeon Pro 555 has 768 shading units, 48 TMUs, and 16 ROPs. This yields pixel rates of 107.7 GPixel/s for NVIDIA versus 13.60 GPixel/s for AMD, and texture rates of 255.8 GTexel/s versus 40.80 GTexel/s.

Power and physical specs diverge completely. The GTX 1070 Ti is a dual-slot card requiring one 8-pin power connector and a 450 W suggested PSU, with a 180 W TDP. The Radeon Pro 555 is an IGP with no power connectors and a 75 W TDP; it has no suggested PSU. The NVIDIA card’s dimensions are 267 mm long, 112 mm high, and 40 mm wide, while the AMD part has no listed dimensions because it is integrated into a portable device.

Bus interface also differs: PCIe 3.0 x16 for NVIDIA versus PCIe 3.0 x8 for AMD. Display outputs are 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.4a on the GTX 1070 Ti, while the Radeon Pro 555 is listed as "Portable Device Dependent." The NVIDIA card supports DirectX 12 (12_1), while the AMD supports DirectX 12 (12_0), a feature-level difference.

Architecture Differences

The GTX 1070 Ti uses the GP104 chip built on a 16 nm TSMC process, while the Radeon Pro 555 uses Polaris 21 on a 14 nm GlobalFoundries process. The NVIDIA architecture is Pascal, and the AMD architecture is GCN 4.0. The transistor counts reflect the size difference: 7,200 million on a 314 mm² die for NVIDIA, versus 3,000 million on a 123 mm² die for AMD. The transistor density is slightly higher on the AMD chip (24.4M / mm² vs. 22.9M / mm²), but the NVIDIA die is more than twice as large.

Neither chip has dedicated ray tracing or tensor cores, as both predate those features. The FP32 performance is 8.186 TFLOPS for the GTX 1070 Ti and 1,305.6 GFLOPS for the Radeon Pro 555. FP16 performance is the key architectural difference: the NVIDIA part offers only 127.9 GFLOPS at a 1:64 ratio, while the AMD part provides 1,305.6 GFLOPS at a 1:1 ratio. This means the Radeon Pro 555 is better suited for workloads that can use half-precision math, though its absolute FP32 numbers are far lower.

The GeForce 10-series generation is the predecessor to GeForce 20, while the Radeon Pro 555 belongs to the Radeon Pro Mac 500 Series. The NVIDIA card’s production status is end-of-life, as is the AMD’s. The GTX 1070 Ti was released in November 2017, and the Radeon Pro 555 in June 2017. The Pascal architecture supports Vulkan 1.4, while GCN 4.0 supports Vulkan 1.3, and both support OpenGL 4.6.
