Architecture Differences

The two GPUs come from entirely different design eras. The RTX A2000 Mobile uses the GA107 chip built on Samsung’s 8 nm process, with 8,700 million transistors packed into a 200 mm² die. The GeForce GTX 670 uses the GK104 chip fabricated by TSMC on a 28 nm process, containing 3,540 million transistors across a 294 mm² die. The A2000 Mobile’s transistor density of 43.5M per mm² is over 3.5 times higher than the GTX 670’s 12.0M per mm².

Architecturally, the A2000 Mobile is based on Ampere, which enables features the Kepler-based GTX 670 cannot offer. The A2000 Mobile supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and includes 20 RT cores and 80 tensor cores for ray tracing and AI workloads. The GTX 670 supports DirectX 12 (11_0) and Vulkan 1.2.175, with no RT or tensor core hardware present. The A2000 Mobile also has explicit FP16 throughput rated at 1:1 with FP32, while the GTX 670 lists no FP16 capability.

The memory subsystems reflect their respective generations. The A2000 Mobile uses 4 GB of GDDR6 at 12 Gbps effective, while the GTX 670 uses 2 GB of GDDR5 at 6 Gbps. Despite the newer memory type, the A2000 Mobile’s 128-bit bus limits bandwidth to 192.0 GB/s, nearly matching the GTX 670’s 192.3 GB/s achieved via a wider 256-bit bus. The A2000 Mobile is an IGP (integrated graphics package) with no power connectors, while the GTX 670 is a dual-slot card requiring two 6-pin connectors and a 450 W suggested PSU. The A2000 Mobile draws 95 W, compared to the GTX 670’s 170 W.

Where Each One Wins

The RTX A2000 Mobile wins every recorded benchmark comparison. In the two head-to-head tests available, it leads by 268.4% in Geekbench OpenCL and 241.7% in Geekbench Vulkan. The A2000 Mobile’s benchmark suite also includes DirectX and PassMark tests where it scores 9611 in G3D, 4334 in GPU compute, and 115 in DirectX 9. These results indicate a card that dominates in raw compute throughput and modern API performance.

The GTX 670, while losing the head-to-head, still has a recorded benchmark set that shows its historical strengths. It has a Geekbench Metal score of 7424, a Geekbench OpenCL score of 15341, and a Geekbench Vulkan score of 15553. In the database’s overall percentile ranking, the GTX 670 sits at 52, only three points below the A2000 Mobile’s 55, which suggests that in legacy workloads or specific driver-optimized scenarios, the older card remains competitive relative to the broader GPU population. However, the direct comparisons show no scenario where the GTX 670 takes the lead.

For use-case analysis, the A2000 Mobile is clearly the better choice for modern workloads: ray-traced rendering, tensor-based compute, and any application leveraging DirectX 12 Ultimate features. The GTX 670’s higher texture rate (109.8 GTexel/s versus 135.0 GTexel/s for the A2000 Mobile) is the only metric where it approaches parity, but its lower pixel rate (27.44 GPixel/s versus 80.98 GPixel/s) and far lower FP32 throughput (2.634 TFLOPS versus 8.637 TFLOPS) cap its ceiling. The GTX 670’s larger physical footprint and higher power draw also make it less suitable for compact or power-constrained systems.

Specification Differences

The two GPUs differ in nearly every measurable specification. The process node moves from 28 nm (GTX 670) to 8 nm (A2000 Mobile). Transistor count rises from 3,540 million to 8,700 million, while die size shrinks from 294 mm² to 200 mm². Clock speeds: the A2000 Mobile runs at 1215 MHz base and 1687 MHz boost, versus 915 MHz base and 980 MHz boost for the GTX 670. Memory clock is 1500 MHz (12 Gbps effective) for the A2000 Mobile and 1502 MHz (6 Gbps effective) for the GTX 670.

Core counts differ substantially. The A2000 Mobile has 2560 shading units, 80 TMUs, 48 ROPs, 20 RT cores, and 80 tensor cores. The GTX 670 has 1344 shading units, 112 TMUs, and 32 ROPs, with no RT or tensor cores. The A2000 Mobile’s pixel rate is 80.98 GPixel/s versus 27.44 GPixel/s, and its texture rate is 135.0 GTexel/s versus 109.8 GTexel/s. FP32 compute is 8.637 TFLOPS for the A2000 Mobile and 2.634 TFLOPS for the GTX 670.

Other differences: TDP is 95 W (A2000 Mobile) versus 170 W (GTX 670). The A2000 Mobile uses PCIe 4.0 x16, the GTX 670 uses PCIe 3.0 x16. Display outputs are portable-device dependent for the A2000 Mobile, while the GTX 670 has 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2. The GTX 670 has physical dimensions of 241 mm length, 111 mm height, and 38 mm width; the A2000 Mobile lists no dimensions as it is an integrated package. The GTX 670 has a launch MSRP of 399 USD; the A2000 Mobile has no launch MSRP recorded. Release dates are 2021-04-11 for the A2000 Mobile and 2012-05-09 for the GTX 670.

Head-to-Head Benchmarks

The database records two direct benchmark comparisons between these GPUs, and the RTX A2000 Mobile wins both decisively.

In Geekbench OpenCL, the A2000 Mobile scores 56518 against the GTX 670’s 15341. This is a delta of 268.4% in favor of the A2000 Mobile. The magnitude of this gap reflects the architectural leap: the A2000 Mobile has nearly 3.3 times the FP32 throughput (8.637 TFLOPS versus 2.634 TFLOPS) and over 1.9 times the shading units (2560 versus 1344). The OpenCL workload also benefits from the A2000 Mobile’s tensor cores and newer memory subsystem, despite the bandwidth being nearly identical. The GTX 670’s GDDR5 memory and Kepler compute layout cannot keep pace with the Ampere design’s parallel execution capabilities.

In Geekbench Vulkan, the A2000 Mobile scores 53146, while the GTX 670 scores 15553. The delta is 241.7% for the A2000 Mobile. Vulkan is a low-level API that exposes hardware capabilities directly, and the results show the A2000 Mobile’s modern feature set, including DirectX 12 Ultimate support and Vulkan 1.4, translates into substantially better frame throughput in compute and graphics workloads. The GTX 670’s Vulkan support (1.2.175) is functional, but the older Kepler architecture lacks the asynchronous compute and resource-management efficiencies of Ampere.

The A2000 Mobile also holds a 55th percentile ranking versus the GTX 670’s 52nd, and its average benchmark score of 13821 exceeds the GTX 670’s 12773 by roughly 8.2%. In the broader context of the database, the A2000 Mobile sits close to the AMD Radeon RX 7900 XT (0.6% ahead) and the AMD Radeon 660M (0.1% ahead), while the GTX 670 is nearly tied with the AMD FirePro W5100 (0.6% behind) and the AMD Radeon Pro 455 (0.4% behind). The performance separation between the two cards is consistent across every measured dimension, with no recorded test where the GTX 670 closes the gap.
