NVIDIA GeForce RTX 4070 vs NVIDIA RTX A2000 Comparison

The Verdict

The benchmark data separates these two NVIDIA cards into distinct roles. The NVIDIA GeForce RTX 4070 wins every recorded head-to-head test, and the margins are decisive. In 3DMark Steel Nomad DX12, the RTX 4070 scores 3,854 against the RTX A2000's 1,345, a 65.1% advantage. The gap persists across compute and graphics APIs: Geekbench OpenCL shows 154,858 versus 67,695, a 56.3% lead, while Geekbench Vulkan shows 174,152 versus 69,089, a 60.3% lead. The RTX A2000 wins zero comparisons in the database.

However, the average benchmark score tells a different story. The RTX A2000 posts an average of 46,043 across all recorded tests, which places it in the 85th percentile of all GPUs. The RTX 4070 averages 37,648, landing in the 81st percentile. This inversion suggests the A2000's strength lies in a narrower set of workloads, likely the professional and compute-oriented tests that dominate its benchmark profile, while the RTX 4070 excels in the gaming and graphics-centric tests where the head-to-head comparisons occur.

The choice depends on the workload. For raw graphics performance, especially DirectX 12 and Vulkan scenarios, the RTX 4070 is the clear pick. For a workstation card with a lower power envelope and a focus on compute density, the RTX A2000 holds its own in the broader database. The data indicates the RTX 4070 is the faster card, but the RTX A2000 is not obsolete; its percentile ranking suggests it remains competitive in its intended professional segment.

Architecture Differences

The two GPUs represent two different NVIDIA architectures and manufacturing approaches. The RTX A2000 uses the GA106 chip on the Ampere architecture, built on Samsung's 8 nm process. The RTX 4070 uses the AD104 chip on the Ada Lovelace architecture, built on TSMC's 5 nm process. This process difference is substantial: the A2000 packs 12,000 million transistors into a 276 mm² die, while the RTX 4070 packs 35,800 million transistors into a 294 mm² die. The transistor density tells the story: 43.5 million transistors per square millimeter for the A2000 versus 121.8 million for the RTX 4070, a 2.8x density advantage for the newer chip.

The core configurations diverge significantly. The RTX A2000 has 3,328 shading units, 104 texture mapping units, and 48 ROPs. The RTX 4070 has 5,888 shading units, 184 TMUs, and 64 ROPs. The RTX 4070 also carries 46 RT cores and 184 tensor cores, while the RTX A2000 has 26 RT cores and 104 tensor cores. These counts translate directly into throughput: the RTX 4070 reaches 29.15 TFLOPS FP32 and FP16, while the RTX A2000 reaches 7.987 TFLOPS in both, a 3.6x raw compute advantage.

Memory architecture also differs. The RTX A2000 uses 6 GB of GDDR6 on a 192-bit bus with 288.0 GB/s bandwidth. The RTX 4070 uses 12 GB of GDDR6X on the same 192-bit bus but with 504.2 GB/s bandwidth. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The A2000 outputs 4x mini-DisplayPort 1.4a, while the RTX 4070 outputs 1x HDMI 2.1 and 3x DisplayPort 1.4a.

Head-to-Head Benchmarks

The database records three direct comparisons, and the RTX 4070 wins all three by wide margins. The largest relative gap appears in 3DMark Steel Nomad DX12, where the RTX 4070's 3,854 score versus the A2000's 1,345 represents a 65.1% difference. This test measures modern DirectX 12 rendering performance, and the RTX 4070's higher shading unit count and clock speeds dominate.

In Geekbench Vulkan, the RTX 4070 scores 174,152 against 69,089, a 60.3% lead. Vulkan is a low-overhead API that scales well with raw GPU resources, and the RTX 4070's 5,888 shading units and 1,920 MHz base clock (versus 562 MHz for the A2000) explain the result. The RTX 4070's boost clock of 2,475 MHz versus 1,200 MHz for the A2000 further widens the gap.

Geekbench OpenCL shows the smallest margin of the three, at 56.3%. The RTX 4070 scores 154,858, while the A2000 scores 67,695. OpenCL is a compute-oriented API, and while the RTX 4070 still wins clearly, the A2000's architecture appears relatively stronger here than in graphics tests. This aligns with the A2000's workstation positioning, where compute efficiency matters more than rasterization speed.

The RTX A2000's average benchmark score of 46,043 versus the RTX 4070's 37,648 suggests the A2000 performs well in tests not covered by the head-to-head list. The database shows the A2000 sits near the NVIDIA RTX 5880 Ada Generation in average score (45,972, a 0.2% difference) and the Intel Arc A730M (45,592, a 1% difference). The RTX 4070's nearest rivals include the NVIDIA Tesla P4 (37,628, a 0.1% difference) and the AMD Radeon RX Vega 56 (37,507, a 0.4% difference), indicating its average is dragged down by older or less demanding tests in its broader profile.

Specification Differences

The cards differ in nearly every measurable specification. The RTX A2000 uses the GA106 chip on Ampere architecture, while the RTX 4070 uses AD104 on Ada Lovelace. The process node moves from 8 nm (Samsung) to 5 nm (TSMC). Transistor count jumps from 12,000 million to 35,800 million, with die size slightly increasing from 276 mm² to 294 mm². Transistor density more than doubles from 43.5M per mm² to 121.8M per mm².

Clock speeds favor the RTX 4070 substantially: base clock 1,920 MHz versus 562 MHz, boost clock 2,475 MHz versus 1,200 MHz. Memory clocks also differ: the A2000 runs at 1,500 MHz with 12 Gbps effective speed, while the RTX 4070 runs at 1,313 MHz but with 21 Gbps effective speed due to GDDR6X. Memory capacity doubles from 6 GB to 12 GB, while bandwidth increases from 288.0 GB/s to 504.2 GB/s.

Core counts all favor the RTX 4070: shading units 5,888 versus 3,328, TMUs 184 versus 104, ROPs 64 versus 48, RT cores 46 versus 26, tensor cores 184 versus 104. Pixel rate rises from 57.60 GPixel/s to 158.4 GPixel/s, and texture rate from 124.8 GTexel/s to 455.4 GTexel/s. FP32 and FP16 both rise from 7.987 TFLOPS to 29.15 TFLOPS.

Power and physical specs diverge. The RTX A2000 has a TDP of 70 W with no power connectors and a suggested PSU of 250 W. The RTX 4070 has a TDP of 200 W, requires one 16-pin connector, and suggests a 550 W PSU. Both are dual-slot cards, but the A2000 is 167 mm long and 69 mm tall, while the RTX 4070 is 240 mm long, 110 mm tall, and 40 mm wide. The A2000 offers 4x mini-DisplayPort 1.4a outputs, while the RTX 4070 offers 1x HDMI 2.1 and 3x DisplayPort 1.4a.

Where Each One Wins

The RTX 4070 wins in every direct comparison recorded. Its 3,854 score in 3DMark Steel Nomad DX12 versus 1,345 for the A2000 makes it the choice for modern DirectX 12 gaming and rendering workloads. The Vulkan result (174,152 versus 69,089) extends this to low-overhead APIs, and the OpenCL result (154,858 versus 67,695) shows compute advantage as well. The RTX 4070's 29.15 TFLOPS FP32 and 504.2 GB/s bandwidth provide the underlying resources for these wins. Its 12 GB memory capacity also doubles the A2000's 6 GB, which matters for larger textures and datasets.

The RTX A2000 wins in the broader database context. Its average benchmark score of 46,043 places it in the 85th percentile of all GPUs, above the RTX 4070's 81st percentile. The A2000's nearest rivals include the RTX 5880 Ada Generation (0.2% difference) and Intel Arc A730M (1% difference), indicating it competes with professional and mobile workstation parts. Its 70 W TDP with no power connectors makes it suitable for systems with limited power delivery, and its 167 mm length fits smaller chassis. The A2000's 4x mini-DisplayPort outputs suit multi-monitor professional setups, while the RTX 4070's single HDMI and three DisplayPort outputs target consumer displays.

The data implies a clear split. For graphics-intensive tasks, especially those using DirectX 12 or Vulkan, the RTX 4070 is the superior card by significant margins. For compute-focused professional workloads, the RTX A2000's higher percentile ranking and proximity to workstation-class rivals suggest it retains value despite its lower raw performance. The RTX 4070's 200 W TDP and 550 W suggested PSU indicate it requires a more substantial system, while the A2000's 70 W TDP and 250 W suggested PSU integrate into lower-power workstations. The physical dimensions reinforce this: the A2000 is 167 mm long and 69 mm tall, while the RTX 4070 is 240 mm long, 110 mm tall, and 40 mm wide. Users with space and power constraints should favor the A2000; users prioritizing maximum graphics throughput should choose the RTX 4070.
