AMD Radeon RX 7650 GRE vs NVIDIA Tesla P4 Comparison

The Verdict

The data separates these two cards into completely different roles. The AMD Radeon RX 7650 GRE is the clear performance winner, sitting at the 83rd percentile of all GPUs with an average benchmark score of 42,723. The NVIDIA Tesla P4, at the 81st percentile, posts an average score of 37,628. That is a 13.5% gap in average score, and in the one direct head-to-head benchmark recorded, Geekbench OpenCL, the RX 7650 GRE more than doubles the Tesla P4, scoring 83,109 against 34,947, a 137.8% advantage.

If you need raw compute, rendering, or gaming-class performance in a modern desktop, the RX 7650 GRE is the only sensible pick from this pair. The Tesla P4 is an end-of-life, 2016-era accelerator with no display outputs, a 75 W power draw, and a single-slot profile. Its only practical use case, based on the recorded data, is as a low-power compute or inference card in a server where the 75 W ceiling and no-output design are assets, not drawbacks. For anyone building a workstation with a monitor attached, the Tesla P4 is disqualified immediately because it has no outputs.

Architecture Differences

The two chips come from different generations and foundry processes. The RX 7650 GRE uses the Navi 33 chip on TSMC's 6 nm process, with 13,300 million transistors on a 204 mm² die. The Tesla P4 uses the GP104 chip on TSMC's 16 nm process, with 7,200 million transistors on a 314 mm² die. The process advantage is stark: the AMD chip packs nearly twice the transistors into a smaller area, giving a transistor density of 65.2M per mm² versus 22.9M per mm².

Architecturally, the RX 7650 GRE is built on RDNA 3.0, while the Tesla P4 is Pascal. The AMD card carries 32 ray tracing cores; the Tesla P4 has none. The AMD card supports DirectX 12 Ultimate (12_2), while the Tesla P4 only reaches DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4, so API compatibility for those two is identical.

The memory subsystems differ in type and width. The RX 7650 GRE uses 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The Tesla P4 also has 8 GB, but it is GDDR5 on a 256-bit bus, delivering 192.3 GB/s. The AMD card has a narrower bus but faster memory, resulting in a 49.8% bandwidth advantage. The Tesla P4 compensates with more shading units, 2560 versus 2048, and more texture mapping units, 160 versus 128, but those units run at much lower clocks.

Clock speeds tell the rest of the story. The RX 7650 GRE boosts to 2695 MHz with a base of 1720 MHz and a game clock of 2350 MHz. The Tesla P4 boosts to just 1114 MHz with an 886 MHz base. That clock difference, combined with the newer architecture, explains the massive FP32 gap: 22.08 TFLOPS for AMD versus 5.704 TFLOPS for NVIDIA. The FP16 numbers are even more lopsided: 22.08 TFLOPS for AMD versus 89.12 GFLOPS for NVIDIA, a 1:1 ratio on RDNA 3.0 versus a 1:64 ratio on Pascal.

Head-to-Head Benchmarks

The only recorded head-to-head test is Geekbench OpenCL. The RX 7650 GRE scores 83,109, and the Tesla P4 scores 34,947. That is a 137.8% delta in favor of AMD. This is not a close race; it is a blowout. The RX 7650 GRE delivers 2.38 times the OpenCL score of the Tesla P4.

Looking at the average benchmark scores, the RX 7650 GRE sits at 42,723, which puts it 1.2% behind the NVIDIA GeForce RTX 4070 SUPER (43,223) and 1.2% behind the NVIDIA Quadro M6000 24 GB (43,262). It is also 1.3% behind the RTX 5050 Mobile (43,268) and the Quadro M6000 (43,301). Those are all near-neighbor results, meaning the RX 7650 GRE is competitive with those cards despite its lower average.

The Tesla P4 averages 37,628, which is 0.1% behind the RTX 4070 (37,648), 0.3% ahead of the Radeon RX Vega 56 (37,507), and 1.3% ahead of the Radeon PRO W6400 (37,157). It trails the RTX 4080 Mobile (38,135) by 1.3%. So the Tesla P4, despite being from 2016, is not a slouch in average score; it lands in the same neighborhood as modern mid-range cards. But that average is still 13.5% below the RX 7650 GRE.

The data also shows the Tesla P4 has a Geekbench Vulkan score of 40,309, which is not recorded for the RX 7650 GRE, so no direct comparison exists there. The RX 7650 GRE has a 3DMark Steel Nomad DX12 score of 2,336, which is not recorded for the Tesla P4. Neither card has a complete benchmark suite, but the one shared test is decisively AMD's.

FAQ

Q: Which card has higher raw compute performance?

A: The RX 7650 GRE delivers 22.08 TFLOPS FP32, while the Tesla P4 delivers 5.704 TFLOPS. The AMD card is 287% higher in FP32 throughput.

Q: Can I use the Tesla P4 for gaming with a monitor?

A: No. The Tesla P4 has no display outputs, so it cannot drive a monitor directly. The RX 7650 GRE has 1x HDMI 2.1 and 3x DisplayPort 2.1 outputs.

Q: Which card is more power efficient?

A: The Tesla P4 has a 75 W TDP versus 170 W for the RX 7650 GRE. However, the RX 7650 GRE delivers far more performance per watt: 22.08 TFLOPS at 170 W versus 5.704 TFLOPS at 75 W.

Q: Both cards have 8 GB of memory. Are they equal?

A: No. The RX 7650 GRE uses GDDR6 on a 128-bit bus for 288.0 GB/s. The Tesla P4 uses GDDR5 on a 256-bit bus for 192.3 GB/s. The AMD card has 49.8% more memory bandwidth.

Q: Does the Tesla P4 support ray tracing?

A: No. The Tesla P4 has no ray tracing cores. The RX 7650 GRE has 32 ray tracing cores.

Q: Which card is better for DirectX 12 Ultimate games?

A: The RX 7650 GRE supports DirectX 12 Ultimate (12_2). The Tesla P4 only supports DirectX 12 (12_1), so it lacks features required for the Ultimate tier.

Where Each One Wins

AMD Radeon RX 7650 GRE wins on: every performance metric recorded. It wins the only head-to-head benchmark by 137.8%. It has higher pixel rate (172.5 GPixel/s versus 71.30 GPixel/s), higher texture rate (345.0 GTexel/s versus 178.2 GTexel/s), and massively higher FP32 and FP16 throughput. It is the only card with display outputs, ray tracing cores, and modern DirectX 12 Ultimate support. Its active production status and 2025 release date mean it is a current product with driver support going forward. It also has a higher average benchmark score, 42,723 versus 37,628, and a higher percentile ranking, 83 versus 81. If you are building a gaming rig, a workstation with a monitor, or any system that needs to output video, the RX 7650 GRE is the unambiguous choice.

NVIDIA Tesla P4 wins on: power draw and physical footprint. Its 75 W TDP requires no power connectors, while the RX 7650 GRE needs a 170 W TDP and a 1x 8-pin connector. The Tesla P4 is single-slot and 168 mm long versus dual-slot and 204 mm long. Its suggested PSU is 250 W versus 450 W. It also has a wider memory bus, 256-bit versus 128-bit, and more shading units, 2560 versus 2048, but those advantages do not translate into benchmark wins. In the recorded data, the Tesla P4 has a Geekbench Vulkan score of 40,309, which the RX 7650 GRE does not have recorded, so that is an unclaimed category. The Tesla P4 is the pick only for a headless server environment where the 75 W ceiling, single-slot size, and lack of display outputs are exactly what is required. It is end-of-life, so it is a legacy part for specific low-power compute tasks, not a general-purpose GPU.
