GPU Comparison

The NVIDIA RTX A4000 Mobile and AMD FirePro W7000 represent two distinct eras of professional graphics, separated by nearly a decade of architectural evolution. The benchmark data reveals a decisive performance gap, with the RTX A4000 Mobile dominating every shared test, yet the FirePro W7000 holds its own in percentile ranking, suggesting that raw compute power tells only part of the story. This analysis explores the implications of these results, examining where each card excels and what the underlying specifications reveal about their respective design philosophies.

Head-to-Head Benchmarks

The head-to-head comparison is stark, with the NVIDIA RTX A4000 Mobile winning both available tests by colossal margins. In Geekbench OpenCL, the RTX A4000 Mobile scores 97,178 against the FirePro W7000's 17,808, representing a 445.7% advantage. This is not a marginal improvement; it is a generational leap that reflects the fundamental differences in compute architecture and memory bandwidth. The OpenCL result suggests that the RTX A4000 Mobile can handle compute-heavy workloads, such as rendering, simulation, or machine learning inference, at roughly five and a half times the speed of the older AMD card.

The Vulkan test tells a similar but slightly less extreme story. The RTX A4000 Mobile scores 73,002, while the FirePro W7000 manages 22,001, giving NVIDIA a 231.8% lead. Vulkan's lower-level API overhead tends to favor newer architectures, and the data confirms this, though the gap is narrower than in OpenCL. This suggests that while the FirePro W7000 can still execute modern graphics APIs, its older GCN 1.0 design struggles to extract the same level of performance from them. For a professional user working with Vulkan-based applications, the RTX A4000 Mobile offers more than triple the throughput.

Examining the broader benchmark context, the RTX A4000 Mobile's average benchmark score is 21,379, placing it at the 66th percentile of all GPUs. Its nearest rival is the NVIDIA Quadro RTX 5000, which scores 21,629, a -1.2% delta, indicating they are essentially performance peers. The FirePro W7000, meanwhile, averages 19,905 and sits at the 65th percentile, with its closest competitor being the NVIDIA Tesla K40m at 19,885 (+0.1%). Despite the massive head-to-head disparity, the percentile rankings are nearly identical, which implies that the FirePro W7000 remains competitive within its own performance tier, even if that tier is far below the modern mobile workstation card.

Architecture Differences

The architectural gap between these two GPUs is vast, beginning with the manufacturing process. The RTX A4000 Mobile uses an 8 nm process at Samsung, while the FirePro W7000 relies on TSMC's 28 nm node. This process shrink allows the NVIDIA chip, GA104, to pack 17,400 million transistors onto a 392 mm² die, achieving a transistor density of 44.4 million per square millimeter. The AMD Pitcairn chip, by contrast, contains only 2,800 million transistors on a 212 mm² die, with a density of 13.2 million per square millimeter. The RTX A4000 Mobile's density advantage of over three times is a direct result of newer manufacturing technology, enabling far more complex logic in the same physical space.

Compute resources differ dramatically. The RTX A4000 Mobile features 5,120 shading units, 160 texture mapping units, and 80 ROPs, alongside 40 dedicated ray tracing cores and 160 tensor cores. The FirePro W7000 has 1,280 shading units, 80 TMUs, and 32 ROPs, with no ray tracing or tensor core support whatsoever. This means the NVIDIA card can handle hardware-accelerated ray tracing and AI-driven tasks like DLSS, while the AMD card is purely a rasterization and compute device. The FP32 throughput reflects this: the RTX A4000 Mobile delivers 17.20 TFLOPS, while the FirePro W7000 manages just 2.432 TFLOPS, a 7x difference in raw floating-point performance.

Memory subsystems also diverge sharply. The RTX A4000 Mobile uses 8 GB of GDDR6 on a 256-bit bus, yielding 384.0 GB/s of bandwidth. The FirePro W7000 has 4 GB of GDDR5 on the same 256-bit bus, but only achieves 153.6 GB/s. The effective memory clock rates are 12 Gbps versus 4.8 Gbps, explaining the bandwidth gap. For large datasets or high-resolution textures, the RTX A4000 Mobile can feed its compute units more than twice as fast, a critical factor in professional workloads. The FirePro W7000 also lacks FP16 support, while the RTX A4000 Mobile offers FP16 at a 1:1 ratio with FP32, enabling faster mixed-precision compute.

The bandwidth difference (384.0 vs 153.6 GB/s) further compounds this advantage.

Q: Are these cards comparable in their overall performance percentiles?

A: Surprisingly, yes. The RTX A4000 Mobile is at the 66th percentile of all GPUs, and the FirePro W7000 is at the 65th. This is because the percentile ranks against all GPUs, and the FirePro W7000's average score of 19,905 is within 7% of the RTX A4000 Mobile's 21,379, despite the head-to-head benchmarks showing a much larger gap.

Q: What does the transistor density difference indicate about efficiency?

A: The RTX A4000 Mobile's 44.4 million transistors per mm² versus the FirePro W7000's 13.2 million reflects a much more advanced manufacturing process. This allows the NVIDIA card to deliver higher performance within a lower 115 W TDP, compared to the AMD card's 150 W TDP, suggesting better performance-per-watt.

Specification Differences

The two cards differ in nearly every measurable specification. The RTX A4000 Mobile uses an 8 nm Samsung process, while the FirePro W7000 uses a 28 nm TSMC process. Transistor counts are 17,400 million versus 2,800 million, and die sizes are 392 mm² versus 212 mm². The NVIDIA chip has 5,120 shading units, 160 TMUs, and 80 ROPs, compared to 1,280 shading units, 80 TMUs, and 32 ROPs on the AMD chip. The RTX A4000 Mobile features 40 RT cores and 160 tensor cores; the FirePro W7000 has neither.

Clock speeds differ, with the RTX A4000 Mobile running at a 1140 MHz base and 1680 MHz boost, while the FirePro W7000 has no listed base or boost clocks. Memory configurations are also distinct: 8 GB GDDR6 at 12 Gbps effective versus 4 GB GDDR5 at 4.8 Gbps effective. Bandwidth is 384.0 GB/s versus 153.6 GB/s. Pixel and texture rates are far higher on the NVIDIA card: 134.4 GPixel/s and 268.8 GTexel/s, versus 30.40 GPixel/s and 76.00 GTexel/s. FP32 compute is 17.20 TFLOPS versus 2.432 TFLOPS, and FP16 is 17.20 TFLOPS on the NVIDIA card versus none on the AMD card.

Power and physical specs also vary. The RTX A4000 Mobile has a 115 W TDP and no power connectors, while the FirePro W7000 has a 150 W TDP, a 1x 6-pin connector, and a suggested PSU of 450 W. The AMD card is a single-slot design measuring 242 mm in length and 111 mm in height, with four DisplayPort 1.2 outputs; the NVIDIA card's display outputs are listed as portable device dependent. The bus interface is PCIe 4.0 x16 on the RTX A4000 Mobile versus PCIe 3.0 x16 on the FirePro W7000. API support differs, with the NVIDIA card supporting DirectX 12 Ultimate (12_2) and Vulkan 1.4, versus DirectX 12 (11_1) and Vulkan 1.2.170 on the AMD card.

Where Each One Wins

The RTX A4000 Mobile wins decisively in every benchmark category where data exists. Its OpenCL and Vulkan scores are multiple times higher, making it the clear choice for compute-heavy tasks such as GPU-accelerated rendering, scientific simulation, or any workload that leverages FP32 throughput. The 8 GB memory capacity and 384.0 GB/s bandwidth enable handling of large datasets without bottlenecks. The presence of RT and tensor cores opens up ray-traced rendering and AI-accelerated workflows that the FirePro W7000 simply cannot execute efficiently.

The FirePro W7000's strengths lie in its legacy compatibility and physical design. As a single-slot card with four DisplayPort 1.2 outputs, it can drive multiple displays in a workstation setup without occupying excessive space. Its 150 W TDP, while higher than the RTX A4000 Mobile's 115 W, is manageable with a standard 450 W PSU. For older software that predates modern APIs, the FirePro W7000's GCN architecture may have mature driver support that is more stable in legacy environments. Its 65th percentile ranking, nearly matching the RTX A4000 Mobile's 66th, indicates that in the broader GPU landscape, it is not an obsolete part, it still outperforms many contemporary cards in average score.

The Verdict

The data overwhelmingly favors the NVIDIA RTX A4000 Mobile for any modern professional workload. Its 445.7% lead in OpenCL and 231.8% lead in Vulkan are not incremental improvements; they represent a fundamental shift in capability. Users who need maximum compute performance, ray tracing, or AI features should choose the RTX A4000 Mobile without hesitation. Its higher transistor count, newer architecture, and superior memory subsystem make it the only viable option for demanding tasks like real-time rendering or deep learning inference.

The AMD FirePro W7000, however, remains a reasonable choice for specific legacy scenarios. If the workflow relies on software that predates the RTX A4000 Mobile's release era, or if the physical form factor of a single-slot card with multiple DisplayPort outputs is a hard requirement, the FirePro W7000 can still serve. Its comparable percentile ranking suggests that it is not a performance outlier in the broader market, even if it lags far behind the newer NVIDIA card in direct comparison. For users on a strict budget or with fixed hardware constraints, the FirePro W7000 offers a functional, if dated, professional graphics solution. But for anyone asking which card is faster, the answer is unambiguous: the RTX A4000 Mobile, by a margin that borders on incomparable.
