Analysis: AMD FirePro D300 vs AMD Radeon RX 6600

The AMD FirePro D300 and the AMD Radeon RX 6600 represent two distinct eras of AMD graphics technology, with the former being a 2014 workstation part and the latter a 2021 consumer gaming card. The data reveals a generational chasm in performance, but the specific benchmark results also highlight how different workloads can yield wildly different outcomes. The FirePro D300, despite its age and professional pedigree, put up a respectable fight in one compute test, while the RX 6600 utterly dominated in the other.

Head-to-Head Benchmarks

The head-to-head benchmark data is strikingly lopsided, but the score gaps tell a nuanced story. In Geekbench OpenCL, the AMD Radeon RX 6600 secured a decisive victory with a score of 28,850 against the FirePro D300’s 19,515. This represents a 32.4% performance advantage for the newer card. While this is a significant margin, it is noteworthy that the FirePro D300, with its older GCN architecture and much lower transistor count, managed to stay within a third of the newer card's score. This suggests that the FirePro’s compute-oriented design was still capable in raw number-crunching, even if it couldn't keep pace with the architectural advancements of RDNA 2.

The second benchmark, Geekbench Vulkan, tells an entirely different story of complete and utter dominance. Here, the Radeon RX 6600 scores 67,623, a staggering 70.8% higher than the FirePro D300’s 19,759. This massive delta is not just a win; it is a revelation about the architectural priorities of each card. The FirePro D300’s GCN 1.0 architecture was never designed for the modern Vulkan API, while the RX 6600 is built to excel in it. The RX 6600 doesn’t just win this test; it obliterates the older card’s score, indicating a fundamental leap in how efficiently the newer GPU handles modern graphics workloads and driver-level optimizations.

The Verdict

The benchmark results are unambiguous: the AMD Radeon RX 6600 is the superior performer in both tested scenarios. It holds a 32.4% lead in OpenCL and a 70.8% lead in Vulkan. For any user prioritizing raw compute power or modern graphics API performance, the RX 6600 is the clear choice. The data suggests that the FirePro D300, while once a capable workstation card, is now outclassed in every measurable way. Its only comparative advantage lies in its historical context, but from a pure performance standpoint, the RX 6600 is the definitive winner. The Verdict is simple: the data says the Radeon RX 6600 is the card to pick for anyone looking for a functional, modern GPU.

Architecture Differences

The architectural chasm between these two GPUs is the primary driver of their performance disparity. The FirePro D300 is built on GCN 1.0 architecture, while the RX 6600 utilizes RDNA 2.0. This fundamental difference is reflected in their manufacturing processes, with the FirePro using a 28 nm node and the RX 6600 using a much more advanced 7 nm node, both from TSMC. This process shrink has allowed AMD to pack a significantly larger number of transistors into the Navi 23 chip.

The chip designs are also vastly different. The FirePro D300 uses the Pitcairn chip, which contains 2,800 million transistors on a 212 mm² die. In contrast, the RX 6600 uses the Navi 23 chip, which packs a massive 11,060 million transistors into a 237 mm² die. This increase in transistor density is staggering, going from 13.2M / mm² on the older chip to 46.7M / mm² on the newer one. This density directly translates to the RX 6600 having more of everything: 1,792 shading units, 112 texture mapping units, and 64 ROPs, compared to the FirePro’s 1,280 shaders, 80 TMUs, and 32 ROPs. Furthermore, the RX 6600 includes 28 ray tracing cores, a feature entirely absent from the FirePro D300. The RX 6600 also supports a newer version of DirectX (12 Ultimate) and Vulkan 1.4, whereas the FirePro is limited to DirectX 12 (11_1) and Vulkan 1.2.170.

Specification Differences

Beyond the core architecture, the two cards diverge significantly on memory and power specifications. The most obvious difference is memory capacity: the FirePro D300 has 2 GB of GDDR5, while the RX 6600 has 8 GB of GDDR6. Although the RX 6600 uses a narrower 128-bit memory bus compared to the FirePro’s 256-bit bus, the much faster GDDR6 memory on the RX 6600 (at 14 Gbps effective) results in higher bandwidth of 224.0 GB/s versus the FirePro’s 162.6 GB/s. The RX 6600 also has significantly higher clock speeds, with a base clock of 1626 MHz and a boost clock of 2491 MHz, whereas the FirePro D300 has no base or boost clock listed in the data.

Power and physical characteristics also differ. The RX 6600 has a lower TDP of 132 W compared to the FirePro’s 150 W, and it requires a single 8-pin power connector, while the FirePro’s connector info is not specified. The RX 6600’s suggested PSU is 300 W, lower than the FirePro’s 450 W. The RX 6600 is also a Dual-slot card measuring 190 mm in length, while the FirePro D300 is a Single-slot card that is longer at 242 mm. The bus interface also differs, with the RX 6600 using the newer PCIe 4.0 x8 interface versus the FirePro’s PCIe 3.0 x16. Lastly, the RX 6600 offers a more modern set of display outputs, including 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the FirePro D300 provides 4x DisplayPort 1.2.

FAQ

Q: Which GPU is faster in OpenCL compute workloads?

A: The AMD Radeon RX 6600 is significantly faster, scoring 28,850 in Geekbench OpenCL compared to the FirePro D300’s 19,515, a 32.4% difference.

Q: How big is the performance gap in Vulkan graphics tests?

A: The gap is enormous. The Radeon RX 6600 scores 67,623 in Geekbench Vulkan, which is 70.8% higher than the FirePro D300’s score of 19,759.

Q: Which card has more memory?

A: The Radeon RX 6600 has 8 GB of GDDR6 memory, while the FirePro D300 has only 2 GB of GDDR5.

Q: Are these cards from the same generation of technology?

A: No. The FirePro D300 is from the GCN 1.0 era, while the RX 6600 is from the RDNA 2.0 era. The RX 6600 also has a more advanced manufacturing process (7 nm vs 28 nm).

Q: Does the Radeon RX 6600 support hardware ray tracing?

A: Yes, the RX 6600 has 28 ray tracing cores. The FirePro D300 has no ray tracing cores listed in its specifications.

Q: Which card has a higher average benchmark score?

A: The FirePro D300 has a slightly higher average benchmark score of 19,637 compared to the RX 6600’s 19,036, despite losing in the head-to-head tests.

Where Each One Wins

According to the head-to-head data, the AMD Radeon RX 6600 is the winner in every category tested. It is the clear choice for any modern workload, particularly those that leverage the Vulkan API, where its 70.8% lead is insurmountable. Its sheer performance advantage in OpenCL also makes it the superior choice for general-purpose compute tasks. The RX 6600’s modern feature set, including ray tracing cores and a newer API level, makes it a far more future-proof option.

The AMD FirePro D300, on the other hand, finds its niche not in performance but in its specific characteristics. Its single-slot design and 4x DisplayPort 1.2 outputs could be appealing in specific multi-display workstation setups where space is at a premium. Its lower transistor density and older architecture suggest it might be more focused on raw compute throughput per clock in legacy applications. However, the data shows that it loses the only two benchmarks where they are directly compared. For those considering this card, the only wins are its form factor and its historical context as a professional FirePro part, but not in any head-to-head performance metric.
