Q: What is the memory capacity difference between the two cards?

A: The AMD Radeon RX 6750 GRE 12 GB has 12 GB of GDDR6 memory, while the NVIDIA RTX A2000 has 6 GB of GDDR6 memory. Both use a 192-bit memory bus, but the AMD card delivers 432.0 GB/s of bandwidth versus 288.0 GB/s for the NVIDIA card.

Q: What are the power requirements for each card?

A: The AMD Radeon RX 6750 GRE 12 GB has a TDP of 250 W and requires a 600 W suggested power supply, using a 1x 6-pin plus 1x 8-pin power connector setup. The NVIDIA RTX A2000 has a TDP of 70 W, requires a 250 W suggested power supply, and needs no power connectors.

Q: Which card is better suited for professional workstation environments?

A: The NVIDIA RTX A2000 is part of the Workstation Ampere generation, supports 4x mini-DisplayPort 1.4a outputs, and includes 104 tensor cores. However, the AMD card has a higher average benchmark score and wins both direct comparisons, so for raw performance, the AMD card is ahead, while the RTX A2000 offers a lower-power, compact form factor.

Q: What is the size difference between the two cards?

A: The AMD Radeon RX 6750 GRE 12 GB measures 267 mm in length, 110 mm in height, and 40 mm in width. The NVIDIA RTX A2000 measures 167 mm in length and 69 mm in height, with no width listed.

The Verdict

The data points to a clear performance hierarchy. The AMD Radeon RX 6750 GRE 12 GB wins both head-to-head benchmark tests, holds a higher average benchmark score, and ranks higher in the percentile distribution. For anyone prioritizing gaming or compute performance, the AMD card is the stronger choice based on recorded measurements.

The NVIDIA RTX A2000, however, occupies a different niche. It is an end-of-life workstation card with a 70 W TDP, no power connectors, and a compact 167 mm length. Builders assembling a small-form-factor system or a low-power workstation should consider the RTX A2000 for its physical and electrical footprint. The AMD card, by contrast, is a dual-slot, 250 W card that demands a 600 W power supply.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The decision comes down to performance versus power envelope.

Head-to-Head Benchmarks

The recorded head-to-head results are unambiguous. In 3DMark Steel Nomad DX12, the AMD Radeon RX 6750 GRE 12 GB scores 2402, while the NVIDIA RTX A2000 scores 1345. That is a 78.6% advantage for the AMD card. This is the largest single gap in the comparison.

In Geekbench Vulkan, the AMD card scores 108994 versus 69089 for the RTX A2000, a 57.8% lead. The AMD card wins both direct comparisons, for a total of 2 wins and 0 losses.

The average benchmark scores corroborate this picture. The AMD card averages 55698, which places it just 0.1% behind the AMD Radeon 8060S and 0.7% behind the NVIDIA GeForce RTX 5080 in the nearest rivals list. It also sits 1.6% ahead of the AMD Radeon Pro W5700X and 2.7% ahead of the NVIDIA GeForce RTX 4080. The RTX A2000 averages 46043, putting it 0.2% ahead of the NVIDIA RTX 5880 Ada Generation and 1% ahead of the Intel Arc A730M, while sitting 1.2% behind both the AMD Radeon RX 5600M and the Intel Arc A530M.

The percentile ranks reflect the same ordering. The AMD card is at the 87th percentile among all GPUs, while the RTX A2000 is at the 85th. The performance gap in the head-to-head tests is far larger than the percentile difference suggests, which indicates the RTX A2000 benefits from a broad but shallow benchmark profile.

Specification Differences

The two cards differ substantially across nearly every specification category.

The AMD Radeon RX 6750 GRE 12 GB uses the Navi 22 chip built on TSMC's 7 nm process, with 17,200 million transistors on a 335 mm² die. The NVIDIA RTX A2000 uses the GA106 chip built on Samsung's 8 nm process, with 12,000 million transistors on a 276 mm² die. The transistor density is 51.3 million per mm² for the AMD card and 43.5 million per mm² for the NVIDIA card.

Clock speeds diverge sharply. The AMD card has a base clock of 2321 MHz, a boost clock of 2581 MHz, and a game clock of 2439 MHz. The RTX A2000 has a base clock of 562 MHz and a boost clock of 1200 MHz, with no game clock listed. Memory clocks also differ: the AMD card runs at 2250 MHz with 18 Gbps effective, while the RTX A2000 runs at 1500 MHz with 12 Gbps effective.

Memory capacity and bandwidth favor AMD. The RX 6750 GRE has 12 GB of GDDR6 with 432.0 GB/s of bandwidth. The RTX A2000 has 6 GB of GDDR6 with 288.0 GB/s of bandwidth. Both use a 192-bit bus.

Compute configurations differ in interesting ways. The RTX A2000 has more shading units (3328 versus 2560) and includes 104 tensor cores, while the AMD card has none. The AMD card has more TMUs (160 versus 104) and more ROPs (64 versus 48). The RTX A2000 has 26 RT cores versus 40 for the AMD card.

Pixel and texture rates favor the AMD card. The RX 6750 GRE delivers 165.2 GPixel/s and 413.0 GTexel/s, while the RTX A2000 delivers 57.60 GPixel/s and 124.8 GTexel/s. FP32 throughput is 13.21 TFLOPS for AMD versus 7.987 TFLOPS for NVIDIA. FP16 throughput is 26.43 TFLOPS (2:1) for AMD versus 7.987 TFLOPS (1:1) for NVIDIA.

Power and physical specs diverge completely. The AMD card has a 250 W TDP and requires a 600 W suggested PSU. The RTX A2000 has a 70 W TDP and requires a 250 W suggested PSU, with no power connectors. Display outputs are 1x HDMI 2.1 and 3x DisplayPort 1.4a for AMD, versus 4x mini-DisplayPort 1.4a for NVIDIA. The AMD card is 267 mm long, 110 mm tall, and 40 mm wide. The RTX A2000 is 167 mm long and 69 mm tall.

Architecture Differences

The architectural split is a story of process, design priorities, and feature sets.

The AMD Radeon RX 6750 GRE 12 GB is built on RDNA 2.0 architecture, fabricated on TSMC's 7 nm process. The chip, Navi 22, contains 17,200 million transistors on a 335 mm² die. The NVIDIA RTX A2000 uses Ampere architecture, fabricated on Samsung's 8 nm process. Its GA106 chip contains 12,000 million transistors on a 276 mm² die. The AMD process node is denser, at 51.3 million transistors per mm² versus 43.5 million for NVIDIA.

The RTX A2000 carries 104 tensor cores, a feature entirely absent from the AMD card. This makes the NVIDIA card the only one of the two with dedicated hardware for tensor workloads. The RT core counts also differ: 40 for AMD versus 26 for NVIDIA.

The AMD card is a Radeon RX 6000 series product from the Navi II generation, released on 2023-10-16. The RTX A2000 belongs to the Workstation Ampere generation, released on 2021-08-09. The AMD card is still in active production, while the RTX A2000 is marked end-of-life.

The memory architecture shows a notable divergence in FP16 handling. The AMD card runs FP16 at 26.43 TFLOPS using a 2:1 ratio relative to FP32, while the RTX A2000 runs FP16 at 7.987 TFLOPS with a 1:1 ratio. This means the AMD card can double its FP16 throughput, while the NVIDIA card does not.

Where Each One Wins

The AMD Radeon RX 6750 GRE 12 GB wins on raw performance. It takes both head-to-head benchmarks, leads in average benchmark score, and ranks higher in the overall percentile distribution. It also offers double the memory capacity (12 GB versus 6 GB) and 50% more memory bandwidth (432.0 GB/s versus 288.0 GB/s). For gaming, 3D rendering, or any workload that scales with raw throughput, the AMD card is the clear winner in the database results.

The NVIDIA RTX A2000 wins on power efficiency and physical footprint. Its 70 W TDP is less than one-third of the AMD card's 250 W TDP. It requires no power connectors and only a 250 W suggested PSU, versus a 600 W suggested PSU for the AMD card. Its 167 mm length is roughly 100 mm shorter than the AMD card's 267 mm. For compact workstation builds, multi-GPU setups, or systems with limited power delivery, the RTX A2000 is the more practical choice.

The tensor cores give the RTX A2000 a unique capability that the AMD card cannot match. Any workload that requires tensor core acceleration, such as certain AI or machine learning inference tasks, would need the NVIDIA card. The AMD card counters with higher FP32 and FP16 throughput, which benefits general compute and graphics workloads.

In terms of longevity, the AMD card is still in active production, while the RTX A2000 is end-of-life. The AMD card also has a newer release date, coming from the Navi II generation versus the older Workstation Ampere generation. For a new build, the AMD card offers an active product with a clear successor path. For a legacy workstation or a low-power appliance, the RTX A2000 retains its niche.
