AMD FirePro D300 vs NVIDIA TITAN Xp Comparison

The AMD FirePro D300 and NVIDIA TITAN Xp represent two very different eras of GPU design, with the former built for professional compute at a modest scale and the latter engineered as a high-end consumer flagship. Benchmark data shows the TITAN Xp dominates in raw performance, yet the FirePro D300 holds its own in specific legacy workloads. This analysis relies strictly on the provided fact pack to break down where each card wins, loses, and why.

The Verdict

The NVIDIA TITAN Xp is the clear performance winner in every head-to-head benchmark recorded. In Geekbench OpenCL, it scores 72,585 against the FirePro D300’s 19,515, a delta of -73.1% for the AMD card. In Geekbench Vulkan, the gap widens further: 87,180 versus 19,759, a -77.3% delta. For any workload that leverages modern compute APIs or raw throughput, the TITAN Xp is the only rational choice from this data.

However, the FirePro D300 is not without a niche. Its average benchmark score of 19,637 places it in the 64th percentile of all GPUs, identical to the TITAN Xp’s percentile ranking. That parity in percentile, despite a massive raw score gap, suggests the FirePro D300 sits near the top of its own performance class—older professional cards with similar legacy feature sets. It also matches closely with the NVIDIA Quadro K5200 (19,602, delta 0.2%) and the AMD Radeon RX 6650 XT (19,765, delta -0.6%). For users constrained to a single-slot, 150 W, 2 GB frame buffer workstation environment with four DisplayPort outputs, the FirePro D300 remains a viable legacy option. The TITAN Xp, with its 250 W TDP, dual-slot footprint, and 12 GB GDDR5X memory, targets a different buyer entirely: one who prioritizes compute density over power efficiency or physical footprint.

Pick the TITAN Xp if you need maximum FP32 throughput, large memory capacity, or modern API support. Pick the FirePro D300 only if your software stack is locked to older GCN-era drivers and you require a specific single-slot form factor with four DisplayPort 1.2 outputs. The data offers no scenario where the FirePro D300 outperforms the TITAN Xp in raw speed.

Architecture Differences

The two cards share a foundry—TSMC—but diverge on every other architectural front. The FirePro D300 uses the Pitcairn chip built on GCN 1.0 architecture, fabricated on a 28 nm process. It packs 2,800 million transistors into a 212 mm² die, yielding a transistor density of 13.2 million per mm². The TITAN Xp, in contrast, employs the GP102 chip on Pascal architecture, using a 16 nm process. It contains 11,800 million transistors across a 471 mm² die, with a density of 25.1 million per mm². That’s over four times the transistor count on a die that is roughly 2.2 times larger.

Core resources differ dramatically. The FirePro D300 has 1,280 shading units, 80 texture mapping units, and 32 ROPs. The TITAN Xp more than triples those figures: 3,840 shading units, 240 TMUs, and 96 ROPs. Neither card includes dedicated ray tracing or tensor cores, so both rely on traditional rasterization pipelines. Clock speeds also favor the TITAN Xp, which has a base clock of 1405 MHz and a boost of 1582 MHz; the FirePro D300 lists no base or boost clock in the data. Memory clocks show a similar split: the FirePro D300 runs at 1270 MHz (5.1 Gbps effective), while the TITAN Xp runs at 1426 MHz (11.4 Gbps effective).

The memory subsystem is where the TITAN Xp pulls further ahead. It offers 12 GB of GDDR5X on a 384-bit bus, yielding 547.6 GB/s of bandwidth. The FirePro D300 has just 2 GB of GDDR5 on a 256-bit bus, delivering 162.6 GB/s. That’s a 3.37x bandwidth advantage for the TITAN Xp. Pixel rate and texture rate follow suit: the TITAN Xp hits 151.9 GPixel/s and 379.7 GTexel/s, versus the FirePro D300’s 27.20 GPixel/s and 68.00 GTexel/s. FP32 compute is 12.15 TFLOPS for the TITAN Xp versus 2.176 TFLOPS for the FirePro D300, a 5.6x gap. The TITAN Xp also lists FP16 at 189.8 GFLOPS (1:64 ratio), while the FirePro D300 has no FP16 figure.

API support differs in meaningful ways. The FirePro D300 supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The TITAN Xp supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The higher DirectX feature level and newer Vulkan version on the TITAN Xp indicate better compatibility with recent game and compute titles. Both cards use PCIe 3.0 x16, but display outputs diverge: the FirePro D300 has four DisplayPort 1.2 ports, while the TITAN Xp has one HDMI 2.0 and three DisplayPort 1.4a ports. Power requirements also differ: the FirePro D300 is a single-slot card at 150 W TDP with a suggested 450 W PSU, whereas the TITAN Xp is dual-slot at 250 W TDP, requiring one 6-pin and one 8-pin connector plus a 600 W PSU.

Head-to-Head Benchmarks

The only common benchmarks in the fact pack are Geekbench OpenCL and Geekbench Vulkan, and the TITAN Xp wins both decisively.

In Geekbench OpenCL, the TITAN Xp scores 72,585 against the FirePro D300’s 19,515. That represents a -73.1% delta for the AMD card. To put that in perspective, the FirePro D300’s nearest rival is the NVIDIA Quadro K5200 with an average score of 19,602 (delta 0.2%), and the AMD Radeon RX 6650 XT at 19,765 (delta -0.6%). The TITAN Xp’s OpenCL result is roughly 3.7 times higher than the FirePro D300’s score. This aligns with the FP32 compute gap: 12.15 TFLOPS versus 2.176 TFLOPS. The OpenCL test likely stresses raw shader throughput, where the TITAN Xp’s 3,840 shading units dwarf the FirePro D300’s 1,280.

In Geekbench Vulkan, the margin expands further. The TITAN Xp posts 87,180, while the FirePro D300 manages 19,759—a -77.3% delta. The TITAN Xp’s Vulkan score is 4.4 times higher. This larger gap compared to OpenCL may stem from the TITAN Xp’s newer Vulkan 1.4 support versus the FirePro D300’s Vulkan 1.2.170. The TITAN Xp’s memory bandwidth advantage (547.6 GB/s versus 162.6 GB/s) likely also contributes, as Vulkan workloads often leverage larger buffers. The FirePro D300’s nearest rival in this test would be the Radeon RX 6650 XT (19,765 average), which is only 0.6% higher than the FirePro D300’s OpenCL score, but no Vulkan-specific rival data exists for either card.

Across both tests, the TITAN Xp wins every head-to-head matchup, securing 2 wins to the FirePro D300’s 0. The TITAN Xp’s average benchmark score is 19,177, which is slightly lower than the FirePro D300’s 19,637, but that average includes a broader suite—like Passmark tests where the TITAN Xp scores 18,750 in G3D, 9,430 in GPU compute, and 883 in G2D—whereas the FirePro D300 only has the two Geekbench entries. This discrepancy highlights that average scores alone can mislead; the head-to-head data is unambiguous. The TITAN Xp is faster in every directly comparable workload, and the only question is whether the FirePro D300’s lower power draw, single-slot design, and four DisplayPort outputs justify its existence in legacy professional systems. For pure performance, the data says the TITAN Xp wins without qualification.
