Architecture Differences

The architectural gap between these two GPUs is substantial, reflecting their different release periods and design goals. The RTX 3080 Ti uses the GA102 chip built on NVIDIA's Ampere architecture, fabricated on Samsung's 8 nm process. The FirePro S9300 X2 utilizes the Capsaicin chip based on AMD's GCN 3.0 architecture, manufactured on TSMC's 28 nm node. This process difference is stark: 8 nm versus 28 nm, which contributes heavily to the transistor density disparity. The RTX 3080 Ti packs 28,300 million transistors into a 628 mm² die, yielding a density of 45.1 million transistors per mm². The FirePro S9300 X2 contains 8,900 million transistors spread across a 596 mm² die, resulting in just 14.9 million transistors per mm².

The RTX 3080 Ti is a modern gaming and compute architecture with dedicated ray tracing and tensor hardware. It includes 80 RT cores and 320 tensor cores, features entirely absent from the FirePro S9300 X2, which has no RT cores and no tensor cores. The shader configuration also differs dramatically: the RTX 3080 Ti has 10,240 shading units, while the FirePro S9300 X2 has 4,096. The texture mapping units stand at 320 versus 256, and the render output units at 112 versus 64.

Memory architecture represents another fundamental split. The RTX 3080 Ti uses 12 GB of GDDR6X with a 384-bit bus. The FirePro S9300 X2 uses 4 GB of HBM with a much wider 4096-bit bus, a design choice typical of early high-bandwidth memory implementations. The bus interface also differs: the RTX 3080 Ti uses PCIe 4.0 x16, while the FirePro S9300 X2 uses PCIe 3.0 x16.

The FirePro S9300 X2 is a server-oriented product with no display outputs, while the RTX 3080 Ti offers standard consumer connectivity with one HDMI 2.1 and three DisplayPort 1.4a outputs. The API support reflects the generational difference: the RTX 3080 Ti supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, whereas the FirePro S9300 X2 supports DirectX 12 (12_0) and Vulkan 1.2.170. Both cards support OpenGL 4.6.

Head-to-Head Benchmarks

The recorded head-to-head data contains only two benchmark comparisons, and the RTX 3080 Ti dominates both. In Geekbench OpenCL, the RTX 3080 Ti scores 170,037 against the FirePro S9300 X2's 27,971. This represents a 507.9% advantage for the NVIDIA card, meaning the RTX 3080 Ti delivers more than six times the OpenCL performance of the AMD card in this test. The magnitude of this gap underscores the architectural and generational differences between the two products.

The Geekbench Vulkan result shows a similar pattern, though with a slightly smaller margin. The RTX 3080 Ti scores 192,697, while the FirePro S9300 X2 manages 37,109. The delta here is 419.3% in favor of the RTX 3080 Ti. This Vulkan gap, while still enormous, is narrower than the OpenCL gap, suggesting the FirePro S9300 X2's GCN architecture has relatively better Vulkan scaling compared to its OpenCL performance, though it remains far behind overall.

Beyond these direct comparisons, the broader benchmark suite in the database shows the RTX 3080 Ti's wide-ranging capabilities. It posts scores of 5,077 in 3DMark Steel Nomad DX12, 26,896 in Passmark G3D, and 15,282 in Passmark GPU Compute. The FirePro S9300 X2 has no corresponding entries for these tests in the database, limiting the comparison scope. The RTX 3080 Ti also demonstrates strong legacy API performance with Passmark DirectX 9 at 274, DirectX 10 at 184, DirectX 11 at 223, and DirectX 12 at 110. Its Passmark G2D score is 1,091.

The win count is decisive: 2 wins for the RTX 3080 Ti and 0 for the FirePro S9300 X2. The data shows no benchmark category where the AMD card takes the lead, which aligns with the substantial hardware differences in shading units, memory bandwidth, and process technology.

Specification Differences

The two cards differ across nearly every measurable specification. The process node is a major differentiator: 8 nm from Samsung for the RTX 3080 Ti versus 28 nm from TSMC for the FirePro S9300 X2. Transistor counts are 28,300 million versus 8,900 million, while die sizes are 628 mm² versus 596 mm². Transistor density is 45.1 million per mm² for the NVIDIA card versus 14.9 million per mm² for the AMD card.

Clock speeds show a significant gap. The RTX 3080 Ti has a base clock of 1365 MHz and a boost clock of 1665 MHz, while the FirePro S9300 X2 has no recorded base or boost clocks in the database. Memory clocks differ as well: the RTX 3080 Ti runs at 1188 MHz with 19 Gbps effective, while the FirePro S9300 X2 runs at 500 MHz with 1000 Mbps effective.

Memory specifications diverge sharply. The RTX 3080 Ti has 12 GB of GDDR6X on a 384-bit bus with 912.4 GB/s bandwidth. The FirePro S9300 X2 has 4 GB of HBM on a 4096-bit bus with 512.0 GB/s bandwidth. The AMD card's wider bus does not compensate for its lower clock speed and smaller capacity.

Compute resources favor the RTX 3080 Ti across the board. Shading units are 10,240 versus 4,096. TMUs are 320 versus 256. ROPs are 112 versus 64. The RTX 3080 Ti has 80 RT cores and 320 tensor cores, while the FirePro S9300 X2 has none. Pixel rate is 186.5 GPixel/s versus 62.40 GPixel/s. Texture rate is 532.8 GTexel/s versus 249.6 GTexel/s. FP32 throughput is 34.10 TFLOPS versus 7.987 TFLOPS. The RTX 3080 Ti also has FP16 at 34.10 TFLOPS with a 1:1 ratio, while the FirePro S9300 X2 has no recorded FP16 value.

Power and physical specifications also differ. The RTX 3080 Ti has a TDP of 350 W with a 1x 12-pin connector and a suggested 750 W PSU. The FirePro S9300 X2 has a TDP of 300 W with 2x 8-pin connectors and a suggested 700 W PSU. Both are dual-slot cards. The RTX 3080 Ti measures 285 mm in length, 112 mm in height, and 40 mm in width. The FirePro S9300 X2 measures 267 mm in length and 111 mm in height, with no recorded width. The RTX 3080 Ti has display outputs, while the FirePro S9300 X2 has none.

Where Each One Wins

The RTX 3080 Ti wins in every recorded benchmark category. Its dominance is most pronounced in compute workloads, as evidenced by the 507.9% lead in Geekbench OpenCL and the 419.3% lead in Geekbench Vulkan. For users running OpenCL-based applications such as scientific computing, video rendering, or machine learning workloads, the RTX 3080 Ti delivers vastly superior throughput. The 34.10 TFLOPS of FP32 performance versus 7.987 TFLOPS gives it more than four times the raw compute capability, making it the clear choice for any FP32-intensive task.

The RTX 3080 Ti also wins decisively in gaming and graphics workloads. Its 12 GB of GDDR6X memory with 912.4 GB/s bandwidth provides ample capacity and speed for modern games at high resolutions. The presence of 80 RT cores enables hardware-accelerated ray tracing, a feature the FirePro S9300 X2 lacks entirely. The 320 tensor cores further extend its utility for AI-based features like DLSS. The Passmark G3D score of 26,896 reflects strong overall graphics performance, and the 3DMark Steel Nomad DX12 score of 5,077 confirms modern API capability.

The FirePro S9300 X2 does not win any recorded benchmark, but its design targets a different use case. As a server product with no display outputs, it was built for dense compute deployments rather than interactive graphics. Its 4096-bit memory bus, while paired with slower HBM, provides a wide data path that can benefit certain bandwidth-sensitive server workloads. The 2x 8-pin power configuration and 300 W TDP make it a more modest power draw in absolute terms, though the RTX 3080 Ti's 350 W TDP is not dramatically higher. The FirePro S9300 X2's 4 GB memory capacity, however, severely limits its utility for large datasets, and its 28 nm process means it runs at a significant efficiency disadvantage compared to the RTX 3080 Ti's 8 nm node.

For users choosing between these two cards today, the data is unambiguous. The RTX 3080 Ti is superior in every measurable benchmark, offers modern features like ray tracing and tensor cores, supports current APIs including DirectX 12 Ultimate, and provides display outputs for general-purpose use. The FirePro S9300 X2, despite its higher launch MSRP, delivers a fraction of the performance and lacks the feature set required for contemporary workloads. The RTX 3080 Ti's 83rd percentile ranking among all GPUs compared to the FirePro S9300 X2's 77th percentile further confirms its higher standing in the overall performance hierarchy.
