AMD Radeon PRO W7500 vs NVIDIA GeForce GTX 780 Comparison

Head-to-Head Benchmarks

The benchmark data presents a striking generational gap. Across the two shared tests, the AMD Radeon PRO W7500 decisively outperforms the NVIDIA GeForce GTX 780. In Geekbench OpenCL, the W7500 scores 58,213 against the GTX 780's 22,863, a delta of 60.7% in favor of the AMD card. The Vulkan result is even more lopsided: 68,634 versus 24,514, a 64.3% advantage for the W7500.

These are not marginal wins; they represent a complete reversal of performance hierarchy. Where the GTX 780 was once a flagship, its numbers now place it in a different performance class entirely. The GTX 780's average benchmark score across all recorded tests is 19,164, while the W7500 averages 16,415 across its wider test suite. That the W7500's average is lower despite crushing the GTX 780 in both shared tests reflects the W7500's inclusion of additional DirectX 9, 10, 11, and 12 tests, which drag down its aggregate. The GTX 780 only has three recorded benchmarks, all of them Geekbench variants.

Looking at the percentile rankings, the GTX 780 sits at the 64th percentile of all GPUs in the database, while the W7500 sits at the 59th. This is a curious inversion. Despite winning both head-to-head tests by enormous margins, the W7500's percentile is lower because its benchmark suite includes legacy DirectX tests where it scores modestly (Passmark DirectX 9: 200, DirectX 10: 65, DirectX 11: 125, DirectX 12: 46). The GTX 780 has no such scores recorded, so its percentile is based solely on its stronger Geekbench results.

The nearest rivals for each card further illustrate the positioning. The GTX 780's closest competitor is the NVIDIA TITAN Xp, with an average score of 19,177 and a delta of only -0.1%. The AMD Radeon RX 6600 sits just 0.7% behind the GTX 780's average. For the W7500, the nearest rival is the NVIDIA RTX PRO 6000 Blackwell with a delta of 0%, followed closely by the AMD Radeon RX 5700 XT at 0.3% and the AMD Radeon Pro 5600M at 0.4%. The W7500's average score is essentially tied with these cards, despite its massive wins in the two Geekbench tests.

FAQ

Q: Which card supports newer graphics APIs?

A: The W7500 supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the GTX 780 only supports DirectX 12 (11_0) and Vulkan 1.2.175. Both support OpenGL 4.6.

Q: What are the physical size differences?

A: The GTX 780 is 267 mm long, 111 mm tall, and 38 mm wide, taking a dual-slot width. The W7500 is 216 mm long, 115 mm tall, and 20 mm wide, taking a single-slot width.

Q: Is the GTX 780 still in production?

A: No. The GTX 780 is marked as end-of-life, released on 2013-05-22. The W7500 is active, released on 2023-08-02.

Architecture Differences

The two cards represent fundamentally different design philosophies separated by a decade of silicon evolution. The GTX 780 uses the GK110 chip on NVIDIA's Kepler architecture, built on a 28 nm process at TSMC with 7,080 million transistors on a 561 mm² die. The W7500 uses the Navi 33 chip on AMD's RDNA 3.0 architecture, built on a 6 nm process at TSMC with 13,300 million transistors on a 204 mm² die. This is the single largest architectural gap: the W7500 packs nearly twice the transistors into less than half the silicon area.

The transistor density tells the story even more clearly. The GTX 780 achieves 12.6 million transistors per square millimeter. The W7500 achieves 65.2 million per square millimeter, a 5.2x improvement in packing efficiency. This explains how the W7500 delivers dramatically higher compute performance while consuming only 70 W against the GTX 780's 250 W.

Core counts differ significantly. The GTX 780 has 2,304 shading units, 192 texture mapping units, and 48 raster output units. The W7500 has 1,792 shading units, 112 TMUs, and 64 ROPs. Despite fewer shading units and TMUs, the W7500 achieves higher texture rate (190.4 GTexel/s versus 173.2 GTexel/s) and vastly higher pixel rate (108.8 GPixel/s versus 43.30 GPixel/s) due to its much higher clocks. The W7500 also has 28 ray tracing cores, which the GTX 780 lacks entirely.

Clock speeds are a major differentiator. The GTX 780 runs at 863 MHz base and 902 MHz boost. The W7500 runs at 1500 MHz base and 1700 MHz boost, nearly double the frequency. Memory clocks also differ: the GTX 780 uses 1502 MHz (6 Gbps effective) GDDR5, while the W7500 uses 2000 MHz (16 Gbps effective) GDDR6. The W7500's FP32 throughput of 12.19 TFLOPS is nearly triple the GTX 780's 4.156 TFLOPS. The W7500 also supports FP16 at 24.37 TFLOPS (2:1), a capability the GTX 780 does not expose.

The Verdict

The data is unambiguous. The AMD Radeon PRO W7500 is the superior card by every measurable performance metric in this comparison. It wins both head-to-head benchmarks by margins exceeding 60%, delivers nearly three times the FP32 throughput, and does so at a fraction of the power draw. The GTX 780's only advantages are higher memory bandwidth (288.4 GB/s versus 256.0 GB/s) and a wider memory bus (384-bit versus 128-bit), but these cannot compensate for the W7500's overwhelming compute advantage.

For a user deciding between these two cards today, the choice is clear. The W7500 is an active product with modern API support, including DirectX 12 Ultimate and Vulkan 1.4, while the GTX 780 is end-of-life with legacy API support. The W7500 offers 8 GB of memory versus 3 GB, which is critical for modern workloads. The W7500 is also physically smaller, single-slot versus dual-slot, and requires no external power connectors.

The GTX 780's 64th percentile ranking versus the W7500's 59th percentile is a statistical artifact of different test suites. In directly comparable tests, the W7500 dominates. The GTX 780's nearest rivals include the NVIDIA TITAN Xp and AMD Radeon RX 6600, cards that are themselves generations old. The W7500's nearest rivals include the NVIDIA RTX PRO 6000 Blackwell and AMD Radeon RX 5700 XT, indicating it sits in a more modern performance tier.

Where Each One Wins

The AMD Radeon PRO W7500 wins in every computational benchmark recorded. It is the clear choice for any workload that leverages OpenCL or Vulkan compute, and its 28 ray tracing cores provide hardware acceleration that the GTX 780 cannot offer at all. The W7500's 12.19 TFLOPS of FP32 performance and 24.37 TFLOPS of FP16 performance make it suitable for modern machine learning inference and graphics workloads. Its 8 GB memory capacity handles larger datasets than the GTX 780's 3 GB. The W7500's single-slot design and 70 W TDP make it ideal for compact builds or dense workstation configurations where space and power are constrained. Its four DisplayPort 2.1 outputs support modern high-resolution displays.

The NVIDIA GeForce GTX 780 retains only narrow advantages. Its 288.4 GB/s memory bandwidth exceeds the W7500's 256.0 GB/s, which could benefit memory-bandwidth-bound legacy workloads. Its 384-bit bus provides higher raw throughput per memory transaction. The GTX 780 also has a higher percentile ranking (64th versus 59th) in the database, though this reflects its narrower benchmark suite. For users running very old software that relies on specific Kepler-era optimizations, the GTX 780 might still function, but it is end-of-life with no future driver optimizations expected.

The practical verdict: the W7500 is the only sensible purchase for anyone building a new system. The GTX 780 is a historical artifact, a card that was impressive in 2013 but has been completely superseded. For professional workloads requiring modern API support, ray tracing, or FP16 compute, the W7500 is the only option between these two. For gaming, the GTX 780's lack of DirectX 12 Ultimate support and limited 3 GB memory make it unsuitable for current titles. The data supports a single conclusion: choose the W7500.
