A: The GTX TITAN Z has a TDP of 375 W and requires a 750 W suggested power supply, while the FirePro D300 has a TDP of 150 W and a 450 W suggested power supply. The NVIDIA card draws 225 W more under load.

Q: What is the transistor and die size difference?

A: The GTX TITAN Z uses 7,080 million transistors on a 561 mm² die, while the FirePro D300 uses 2,800 million transistors on a 212 mm² die. The TITAN Z has roughly 2.5 times the transistor count and a die that is about 2.6 times larger.

Architecture Differences

The NVIDIA GeForce GTX TITAN Z is built on the GK110B chip using the Kepler architecture, fabricated by TSMC on a 28 nm process. The AMD FirePro D300 uses the Pitcairn chip with the GCN 1.0 architecture, also on TSMC’s 28 nm node. Both cards share the same process node and foundry, but their internal designs diverge sharply.

The TITAN Z packs 7,080 million transistors across a 561 mm² die, resulting in a transistor density of 12.6M per mm². The FirePro D300 contains 2,800 million transistors on a 212 mm² die, giving it a higher density of 13.2M per mm². Despite the smaller absolute transistor count, the AMD chip packs transistors more tightly per square millimeter.

Shading resources differ substantially. The GTX TITAN Z carries 2,880 shading units, 240 texture mapping units, and 48 ROPs. The FirePro D300 has 1,280 shading units, 80 TMUs, and 32 ROPs. The NVIDIA card provides 2.25 times the shading units, 3 times the texture units, and 1.5 times the ROP count.

Clock behavior also separates the two. The TITAN Z has a base clock of 705 MHz and a boost clock of 876 MHz. The FirePro D300 lists no base or boost clock in the database, only a memory clock of 1270 MHz (5.1 Gbps effective). The TITAN Z’s memory runs at 1750 MHz (7 Gbps effective), which is higher than the FirePro’s memory clock.

The memory subsystem is a major architectural divider. The TITAN Z uses 6 GB of GDDR5 on a 384-bit bus, delivering 336.0 GB/s of bandwidth. The FirePro D300 uses 2 GB of GDDR5 on a 256-bit bus, delivering 162.6 GB/s. That is a 2x difference in bus width and a 107% difference in bandwidth.

Compute throughput follows the same pattern. The TITAN Z achieves 5.046 TFLOPS of FP32 performance, while the FirePro D300 achieves 2.176 TFLOPS. Pixel rate for the TITAN Z is 52.56 GPixel/s versus 27.20 GPixel/s for the FirePro. Texture rate is 210.2 GTexel/s versus 68.00 GTexel/s.

Both cards support DirectX 12 (11_1) and OpenGL 4.6. The TITAN Z supports Vulkan 1.2.175, while the FirePro D300 supports Vulkan 1.2.170, a minor version difference. The TITAN Z offers display outputs of 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2, while the FirePro D300 offers 4x DisplayPort 1.2.

Physical design differs as well. The TITAN Z is a triple-slot card measuring 267 mm in length, 111 mm in height, and 62 mm in width, with 2x 8-pin power connectors. The FirePro D300 is a single-slot card measuring 242 mm in length, with no height or width listed and no power connectors specified. The TITAN Z requires a 750 W power supply, while the FirePro D300 needs only 450 W.

Head-to-Head Benchmarks

The benchmark data records two head-to-head tests, and the NVIDIA GeForce GTX TITAN Z wins both. The Geekbench OpenCL test shows the TITAN Z scoring 25,465 against the FirePro D300’s 19,515, a 30.5% margin. This is the larger of the two deltas, reflecting the TITAN Z’s substantial advantage in raw compute resources.

The Geekbench Vulkan test narrows the gap. The TITAN Z scores 22,006, and the FirePro D300 scores 19,759, giving the NVIDIA card an 11.4% lead. While the TITAN Z still wins, the Vulkan workload appears to be more favorable to the AMD architecture relative to its OpenCL showing. The FirePro D300’s Vulkan score is actually higher than its OpenCL score, while the TITAN Z’s Vulkan score drops by 13.6% from its OpenCL result.

Looking at the average benchmark scores, the TITAN Z’s 23,736 average is 4,099 points higher than the FirePro D300’s 19,637. In percentile terms, the TITAN Z ranks at the 69th percentile of all GPUs, while the FirePro D300 ranks at the 64th. The TITAN Z’s nearest rivals in the database include the NVIDIA GeForce RTX 3080 Mobile at 23,628 (0.5% lower), the AMD Radeon RX 9070 at 23,877 (0.6% higher), the NVIDIA GeForce RTX 3070 Ti Mobile at 23,518 (0.9% lower), and the AMD Radeon RX 6800S at 24,063 (1.4% higher).

The FirePro D300’s nearest rivals are notably different in character. The NVIDIA Quadro K5200 scores 19,602 (0.2% higher), the AMD Radeon RX 6650 XT scores 19,765 (0.6% higher), the AMD Radeon RX 7900 XTX scores 19,410 (1.2% lower), and the NVIDIA Tesla K40m scores 19,885 (1.2% higher). The FirePro D300 sits in a performance cluster within roughly 1.2% of its nearest competitors, while the TITAN Z sits within 1.4% of its own nearest rivals.

The data shows a consistent pattern: the TITAN Z outperforms the FirePro D300 in both recorded workloads, with the OpenCL advantage being particularly pronounced. The TITAN Z records two wins and zero losses in the head-to-head comparison.

The Verdict

The benchmark data is unambiguous. The NVIDIA GeForce GTX TITAN Z outperforms the AMD FirePro D300 in both recorded tests, with a 30.5% lead in OpenCL and an 11.4% lead in Vulkan. The average benchmark scores reinforce this: 23,736 versus 19,637.

For users prioritizing raw compute performance, the TITAN Z is the clear choice. Its 5.046 TFLOPS of FP32 throughput, 336.0 GB/s of memory bandwidth, and 6 GB of VRAM provide a substantial foundation for compute-heavy workloads. The FirePro D300’s 2.176 TFLOPS and 162.6 GB/s bandwidth place it in a lower performance tier, despite its more efficient transistor density.

The FirePro D300 does have advantages in physical footprint and power draw. It is a single-slot card with a 150 W TDP, while the TITAN Z is a triple-slot card with a 375 W TDP. For systems with strict space or power constraints, the FirePro D300 is the more practical option. The FirePro also offers 4x DisplayPort 1.2 outputs, which may suit multi-display professional setups better than the TITAN Z’s 2x DVI, 1x HDMI, and 1x DisplayPort configuration.

The percentile rankings place the TITAN Z at the 69th percentile and the FirePro D300 at the 64th percentile among all GPUs. Both cards are end-of-life products, but the TITAN Z launched later, on 2014-05-27, versus the FirePro D300’s 2014-01-17 release date.

Users who need maximum compute performance and can accommodate the larger card and higher power draw should select the GTX TITAN Z. Users who need a compact, lower-power solution with multiple DisplayPort outputs and are willing to accept roughly 20% lower average performance should consider the FirePro D300. The data does not support any scenario where the FirePro D300 outperforms the TITAN Z in raw benchmark scores.
