Q: What are the rated power consumptions?

A: The NVIDIA GTX TITAN X is rated at 250 W with a suggested 600 W PSU. The AMD FirePro S9300 X2 draws 300 W and requires a 700 W suggested PSU.

Architecture Differences

The NVIDIA GeForce GTX TITAN X is built on the GM200 chip using the Maxwell 2.0 architecture, fabricated on a 28 nm process at TSMC. The AMD FirePro S9300 X2 uses the Capsaicin chip with GCN 3.0 architecture, also on a 28 nm TSMC process. Both cards share the same foundry and node, but their transistor counts differ slightly: NVIDIA packs 8,000 million transistors across a 601 mm² die, while AMD fits 8,900 million into a 596 mm² die. This yields a transistor density of 13.3M per mm² for NVIDIA versus 14.9M per mm² for AMD.

The memory subsystems are fundamentally divergent. NVIDIA employs 12 GB of GDDR5 with a 384-bit bus, reaching 336.6 GB/s. AMD counters with 4 GB of HBM on a 4096-bit bus, delivering 512.0 GB/s. The HBM approach offers much higher bandwidth but half the capacity. AMD's clock speeds are not recorded for base or boost, while NVIDIA lists a 1000 MHz base and 1089 MHz boost. AMD's memory clock is 500 MHz (1000 Mbps effective), compared to NVIDIA's 1753 MHz (7 Gbps effective).

Compute resources differ in raw counts. AMD has 4,096 shading units, 256 TMUs, and 64 ROPs. NVIDIA has 3,072 shading units, 192 TMUs, and 96 ROPs. The pixel rate favors NVIDIA at 104.5 GPixel/s versus 62.40 GPixel/s for AMD. Texture rate slightly favors AMD at 249.6 GTexel/s versus 209.1 GTexel/s. FP32 performance is higher on the AMD card at 7.987 TFLOPS, while NVIDIA reaches 6.691 TFLOPS.

API support shows a split. NVIDIA supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. AMD supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The NVIDIA card has display outputs (1x DVI, 1x HDMI 2.0, 3x DisplayPort 1.2), while the AMD FirePro S9300 X2 has no display outputs, indicating a compute-focused server card. Both use PCIe 3.0 x16 and are dual-slot designs with identical 267 mm length and 111 mm height. NVIDIA requires 1x 6-pin plus 1x 8-pin power; AMD requires 2x 8-pin.

Head-to-Head Benchmarks

The recorded database contains two head-to-head comparisons, both won by the NVIDIA GeForce GTX TITAN X. In Geekbench OpenCL, NVIDIA scores 41,471 against AMD's 27,971. This 48.3% delta is substantial and indicates a major advantage in general compute workloads. The FirePro S9300 X2, despite having 1,024 more shading units and higher FP32 throughput, falls far behind in this test.

Geekbench Vulkan shows a narrower but still decisive gap. NVIDIA scores 49,397, AMD scores 37,109, yielding a 33.1% advantage for NVIDIA. This test likely stresses driver efficiency and API implementation; NVIDIA's newer Vulkan 1.4 support versus AMD's 1.2.170 may contribute. The data shows NVIDIA wins both tests with a combined 2-0 record.

The average benchmark scores place NVIDIA at 36,530, which is 12.3% higher than AMD's 32,540. In percentile terms, NVIDIA sits at the 80th percentile of all GPUs, AMD at the 77th. The nearest rivals for NVIDIA include the AMD Radeon RX 5300M (36,529, 0% delta), NVIDIA T1000 (36,289, 0.7% ahead), AMD Radeon PRO W6400 (37,157, 1.7% behind), and AMD Radeon Pro Duo (35,860, 1.9% ahead). For AMD, the closest competitors are the AMD Radeon RX 590 GME (32,601, 0.2% behind), AMD Radeon RX 7900 GRE (32,456, 0.3% ahead), AMD FirePro S10000 (32,388, 0.5% ahead), and NVIDIA T600 Mobile (32,849, 0.9% behind). Notably, the NVIDIA GTX TITAN X's average score sits close to several modern cards, while the AMD FirePro S9300 X2 aligns with mid-range options.

The Verdict

The benchmark data clearly favors the NVIDIA GeForce GTX TITAN X. It wins both recorded head-to-head tests, with a 48.3% OpenCL advantage and a 33.1% Vulkan advantage. Its average score of 36,530 outperforms AMD's 32,540 by a meaningful margin. The NVIDIA card also holds a higher percentile rank (80th versus 77th) among all GPUs.

For users who need display outputs, the NVIDIA card is the only option, as the AMD FirePro S9300 X2 has none. The NVIDIA card also offers triple the memory capacity (12 GB versus 4 GB), which matters for large datasets. Despite AMD's higher raw FP32 throughput and bandwidth, the actual compute results show NVIDIA dominates. The AMD card's higher TDP (300 W versus 250 W) and larger PSU requirement (700 W versus 600 W) make it less efficient in the data.

The AMD FirePro S9300 X2 does have advantages in specific metrics: higher shading unit count (4,096 versus 3,072), more TMUs (256 versus 192), faster texture rate (249.6 GTexel/s versus 209.1 GTexel/s), and higher memory bandwidth (512.0 GB/s versus 336.6 GB/s). These specifications, however, do not translate into benchmark wins. The only scenario where AMD leads is in theoretical FP32 throughput (7.987 TFLOPS versus 6.691 TFLOPS).

Where Each One Wins

NVIDIA GeForce GTX TITAN X wins in every measured benchmark category. It is the clear choice for general compute workloads, as shown by the 48.3% OpenCL lead. For Vulkan-based applications, it maintains a 33.1% edge. The card also wins on memory capacity, offering 12 GB versus 4 GB, which suits larger working sets. Its lower power draw (250 W versus 300 W) and smaller PSU recommendation make it easier to integrate into existing systems. The presence of display outputs means it can serve as a workstation GPU with video connectivity. The launch MSRP of 999 USD is recorded, and its release date precedes the AMD card by over a year.

AMD FirePro S9300 X2 wins in raw specification comparisons but not in actual benchmarks. Its 512.0 GB/s bandwidth is substantially higher, which could benefit bandwidth-bound workloads that the Geekbench suite does not capture. The higher texture rate (249.6 GTexel/s) and FP32 throughput (7.987 TFLOPS) suggest potential in specific compute tasks. The 4 GB HBM memory, while smaller, offers a different tradeoff profile. It also has a higher transistor density (14.9M per mm² versus 13.3M per mm²), indicating a more compact design. However, the absence of display outputs restricts it to headless server deployments. Its launch MSRP of 5,999 USD is recorded, and it was released later with a successor path through Radeon Pro GCN.

The data indicates that for any user prioritizing measured performance, the NVIDIA card is the definitive choice. For those with specialized bandwidth-sensitive workloads, the AMD card's 512.0 GB/s might be attractive, but the benchmark evidence does not support that expectation. The AMD card's only clear wins are in theoretical specifications, not in recorded results.
