AMD FirePro S7150 vs NVIDIA GeForce RTX 3080 Ti Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep in the direct comparison between these two GPUs. The AMD FirePro S7150 and the NVIDIA GeForce RTX 3080 Ti Mobile were measured in two shared benchmark tests, and NVIDIA claimed victory in both with substantial margins.

In the Geekbench OpenCL test, the NVIDIA GeForce RTX 3080 Ti Mobile scored 117,866 points against the AMD FirePro S7150's 26,543 points. This represents a delta of -77.5% for the AMD side, meaning the NVIDIA part delivered roughly four and a half times the raw compute throughput in this workload. The gap is not incremental; it is a generational chasm that reflects the fundamental differences in their compute architectures and resource allocations.

The Vulkan benchmark tells a similar story, though with a slightly narrower margin. The NVIDIA GPU recorded 107,502 points while the AMD FirePro S7150 managed 29,690 points, yielding a delta of -72.4%. While still a commanding lead for NVIDIA, the smaller percentage gap in Vulkan compared to OpenCL suggests the AMD architecture holds up relatively better in this API, possibly due to its GCN 3.0 design's strength in certain asynchronous compute workloads. Even so, the absolute scores leave no ambiguity about which part is faster.

The overall win tally stands at 0 for AMD and 2 for NVIDIA in these head-to-head tests. The average benchmark score for the AMD FirePro S7150 is 28,117, placing it in the 73rd percentile of all GPUs in the database. The NVIDIA GeForce RTX 3080 Ti Mobile averages 25,740 across its broader test suite, sitting in the 71st percentile. This is an interesting inversion: the NVIDIA part wins the shared tests overwhelmingly, yet its average score across all recorded benchmarks is slightly lower than the AMD part's average. This discrepancy stems from the fact that the AMD part's average is computed from only two tests, both of which are compute-oriented, while the NVIDIA part's average includes a wider range of DirectX and PassMark workloads, some of which pull its mean downward.

Looking at nearest rivals for context, the AMD FirePro S7150 sits within 1% of the NVIDIA GeForce GTX 980 Ti (delta 0.3%), the AMD Radeon Pro W5500X (delta 0.5%), the AMD Radeon RX 7800M (delta 0.8%), and the AMD Radeon Pro Vega 20 (delta 1%). The NVIDIA GeForce RTX 3080 Ti Mobile, meanwhile, is essentially tied with the AMD Radeon Pro W5700 (delta 0.1%) and the AMD FirePro D700 (delta -0.4%), while slightly ahead of the AMD Radeon RX 6700M (delta 0.4%) and slightly behind the AMD FirePro W7100 (delta -0.4%). These rival comparisons confirm that the RTX 3080 Ti Mobile's raw compute is in a different class, but its average score is dragged down by the mixed bag of benchmarks recorded for it.

Where Each One Wins

The NVIDIA GeForce RTX 3080 Ti Mobile is the clear winner in any workload that stresses raw parallel compute throughput. Its OpenCL score of 117,866 is more than four times the AMD part's 26,543, and its Vulkan score of 107,502 nearly quadruples the AMD's 29,690. This positions the NVIDIA part as the choice for compute-heavy tasks such as rendering, simulation, or machine learning inference, where FP32 and FP16 throughput directly translate to performance. The RTX 3080 Ti Mobile also brings dedicated ray tracing cores (58 of them) and tensor cores (232 of them), which the AMD FirePro S7150 lacks entirely. Any application that leverages DirectX 12 Ultimate features, including ray tracing or mesh shaders, will find these hardware units essential.

The AMD FirePro S7150 does not win any recorded benchmark against the RTX 3080 Ti Mobile, so there is no headline performance advantage to claim. However, its profile suggests specific contexts where it may be preferable. As a server-oriented FirePro product with no display outputs, its design targets compute density and remote or virtualized environments rather than client-side rendering. Its 150 W TDP is higher than the NVIDIA part's 115 W, but the AMD card is a single-slot design with a 1x 6-pin power connector, which may fit into certain server chassis with specific power delivery constraints. The AMD part also carries a 2,399 USD launch MSRP, which reflects its positioning as a professional compute accelerator rather than a consumer mobile GPU.

For gaming or real-time graphics on a portable device, the RTX 3080 Ti Mobile is the only sensible option, as the FirePro S7150 has no display outputs and cannot drive a monitor directly. Conversely, for a server blade where GPU compute is accessed over the network or through virtualization, the FirePro S7150's lack of outputs is not a drawback, and its older GCN 3.0 architecture may have mature driver support in specific enterprise stacks. The data does not show any test where the AMD part wins, so any advantage is qualitative and contextual rather than benchmark-driven.

Architecture Differences

The architectural gap between these two GPUs is vast and explains most of the performance delta. The AMD FirePro S7150 uses the Tonga chip based on GCN 3.0 architecture, fabricated on a 28 nm TSMC process. It packs 5,000 million transistors onto a 366 mm² die, yielding a transistor density of 13.7 million transistors per square millimeter. This is an older, larger-node design with a relatively modest feature set by current standards.

The NVIDIA GeForce RTX 3080 Ti Mobile uses the GA103 chip based on Ampere architecture, built on Samsung's 8 nm process. It contains 22,000 million transistors on a 496 mm² die, which computes to 44.4 million transistors per square millimeter. That density is more than three times higher than the AMD part, enabling far more compute resources in a similar physical footprint. The smaller process node also contributes to the NVIDIA part's lower TDP despite its vastly higher performance: 115 W versus 150 W for the AMD card.

The compute resources differ dramatically. The AMD FirePro S7150 has 2,048 shading units, 128 texture mapping units, and 32 raster operation pipelines. The NVIDIA part has 7,424 shading units, 232 TMUs, and 96 ROPs. These numbers explain the pixel rate and texture rate differences: the AMD card produces 29.44 GPixel/s and 117.8 GTexel/s, while the NVIDIA part achieves 121.0 GPixel/s and 292.3 GTexel/s. The NVIDIA GPU also includes 58 ray tracing cores and 232 tensor cores, which have no direct equivalent in the AMD part. The FP32 throughput is 3.768 TFLOPS for AMD versus 18.71 TFLOPS for NVIDIA, a factor of roughly five. For FP16, the AMD part claims 7.537 TFLOPS via a 2:1 ratio, while NVIDIA's 18.71 TFLOPS is at a 1:1 ratio, meaning the NVIDIA part does not sacrifice FP32 throughput to achieve FP16 rates.

The memory subsystems also reflect different design philosophies. The AMD part uses 8 GB of GDDR5 on a 256-bit bus, delivering 160.0 GB/s of bandwidth from a memory clock of 1250 MHz (5 Gbps effective). The NVIDIA part uses 16 GB of GDDR6 on the same 256-bit bus width, but with a memory clock of 2000 MHz (16 Gbps effective), achieving 512.0 GB/s. That is 3.2 times the bandwidth, which is critical for high-resolution textures and large compute datasets.

The API support reflects their respective generations. The AMD card supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The NVIDIA part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The DirectX 12_2 feature level is a significant upgrade, enabling hardware ray tracing and other DX12 Ultimate features that the AMD part cannot handle. The bus interface also differs: the AMD card uses PCIe 3.0 x16, while the NVIDIA part uses PCIe 4.0 x16, doubling the potential host-to-device bandwidth.

Specification Differences

The most salient specification differences between these two GPUs are as follows. The process node is 28 nm for AMD versus 8 nm for NVIDIA, with transistor counts of 5,000 million and 22,000 million respectively. The die size is 366 mm² for AMD and 496 mm² for NVIDIA, with transistor densities of 13.7M/mm² and 44.4M/mm². The NVIDIA part has explicit clock rates: a base clock of 810 MHz and a boost clock of 1260 MHz, while the AMD part lists no base or boost clocks in the database. Memory type differs: GDDR5 versus GDDR6, with capacities of 8 GB and 16 GB, and bandwidths of 160.0 GB/s and 512.0 GB/s. The memory clock is 1250 MHz (5 Gbps effective) for AMD and 2000 MHz (16 Gbps effective) for NVIDIA.

The compute units show stark differences: shading units at 2048 versus 7424, TMUs at 128 versus 232, and ROPs at 32 versus 96. The NVIDIA part has 58 RT cores and 232 tensor cores; the AMD part has none. Pixel rate is 29.44 GPixel/s versus 121.0 GPixel/s, texture rate is 117.8 GTexel/s versus 292.3 GTexel/s, and FP32 throughput is 3.768 TFLOPS versus 18.71 TFLOPS. FP16 performance is 7.537 TFLOPS (2:1) for AMD and 18.71 TFLOPS (1:1) for NVIDIA.
