NVIDIA GeForce RTX 4070 SUPER vs NVIDIA RTX A1000 Mobile Comparison

The NVIDIA RTX A1000 Mobile and the NVIDIA GeForce RTX 4070 SUPER represent two vastly different design philosophies from the same manufacturer. The A1000 Mobile is an end-of-life, power-efficient mobile workstation part built on the older Ampere architecture, while the 4070 SUPER is a high-performance desktop GPU from the Ada Lovelace generation. The benchmark data shows a decisive performance gap, but the analysis reveals more than just a simple victory; it highlights the trade-offs between mobile efficiency and desktop brute force.

Head-to-Head Benchmarks

The head-to-head data is unambiguous in its outcome. In the two shared benchmark tests, the GeForce RTX 4070 SUPER dominates the RTX A1000 Mobile. In Geekbench OpenCL, the RTX 4070 SUPER scores 172,795 against the A1000 Mobile's 48,703. This represents a delta of -71.8% from the perspective of the A1000 Mobile, meaning the desktop card is roughly 3.5 times faster in this compute workload. The result is even more pronounced in Geekbench Vulkan, where the RTX 4070 SUPER scores 205,624 compared to 46,782 for the mobile part, a delta of -77.2%. This indicates that the architecture and clock speed advantages of the 4070 SUPER translate into an even larger lead in graphics API workloads.

To contextualize these scores, it is helpful to look at the overall average benchmark scores. The RTX A1000 Mobile achieves an average score of 47,743, placing it in the 85th percentile of all GPUs. Its nearest rivals are a mixed bag of desktop and mobile parts, including the AMD Radeon RX 6800 XT (48,477, a -1.5% delta) and the AMD Radeon RX 6550M (46,702, a +2.2% delta). This shows that the A1000 Mobile is a competent performer, sitting right at the edge of high-end desktop performance from a previous generation.

Conversely, the RTX 4070 SUPER has a lower average score of 43,223, which is odd given its massive wins in the head-to-head tests. This is because its average is pulled down by a suite of Passmark tests, including low scores in DirectX 9 (344), DirectX 12 (110), and G2D (1184), which are not representative of its full capabilities. Its percentile ranking is 83rd, just slightly below the A1000 Mobile, despite the head-to-head results. The 4070 SUPER's nearest rivals include the NVIDIA Quadro M6000 24 GB (43,262, a -0.1% delta) and the GeForce RTX 4090 Mobile (43,667, a -1% delta), placing it in a high-performance tier.

The data tells a clear story: the RTX 4070 SUPER is in a different performance class. However, the raw numbers for the A1000 Mobile are not embarrassing; they merely reflect its intended role as a mobile workstation GPU, where power efficiency is paramount. The 4070 SUPER's victory is a total one, with wins in both tests, but the magnitude of the win is the key takeaway. It is not a close contest, and the 4070 SUPER is the clear choice for any workload where raw compute and graphics throughput are the primary metrics.

Architecture Differences

The fundamental differences between these two GPUs begin with their underlying architectures. The RTX A1000 Mobile is built on the Ampere architecture, using the GA107 chip manufactured on an 8 nm process at Samsung. In contrast, the RTX 4070 SUPER uses the Ada Lovelace architecture, with the AD104 chip built on a more advanced 5 nm process at TSMC. This process node difference is a primary driver of the performance gap, allowing for significantly higher clock speeds and transistor density.

The physical specifications highlight the scale of this difference. The AD104 chip in the 4070 SUPER contains 35,800 million transistors on a 294 mm² die, resulting in a transistor density of 121.8M per mm². The GA107 chip in the A1000 Mobile is much smaller and denser in terms of total count, with 8,700 million transistors on a 200 mm² die, yielding a density of 43.5M per mm². This means the 4070 SUPER has over four times the transistor count, enabling a massive increase in processing resources.

Clock speeds also tell a tale of two power envelopes. The A1000 Mobile has a base clock of 630 MHz and a boost clock of 1140 MHz, which are kept low to fit within a 60 W TDP. The 4070 SUPER, on the other hand, operates at a base clock of 1980 MHz and a boost clock of 2475 MHz, enabled by its 220 W TDP. This higher power budget also allows for a more substantial cooling solution, as the 4070 SUPER is a dual-slot card requiring a 16-pin power connector and a 550 W power supply, whereas the A1000 Mobile is an IGP with no power connectors.

The memory subsystems are equally divergent. The A1000 Mobile uses 4 GB of GDDR6 memory on a 128-bit bus, providing 176.0 GB/s of bandwidth. The 4070 SUPER uses 12 GB of faster GDDR6X memory on a 192-bit bus, which more than triples the bandwidth to 504.2 GB/s. The 4070 SUPER also has far more execution resources: 7168 shading units, 224 TMUs, and 80 ROPs, compared to the A1000 Mobile's 2048 shading units, 64 TMUs, and 32 ROPs. The ray tracing and tensor core counts are similarly lopsided, with the 4070 SUPER having 56 RT cores and 224 tensor cores versus 16 and 64, respectively. Finally, the 4070 SUPER uses a PCIe 4.0 x16 interface, while the A1000 Mobile is limited to a x8 connection.

The Verdict

The data presents a clear choice based on use case. The NVIDIA GeForce RTX 4070 SUPER is the superior performer in every measurable way, with more memory, higher bandwidth, more cores, and dramatically higher clock speeds. Its FP32 performance of 35.48 TFLOPS is over seven times that of the A1000 Mobile's 4.669 TFLOPS. For any desktop application requiring maximum throughput, such as high-resolution gaming, 3D rendering, or complex scientific simulations, the 4070 SUPER is the definitive choice. Its launch MSRP is 599 USD.

The RTX A1000 Mobile, however, serves a distinct purpose. Its 60 W TDP and IGP form factor make it suitable for mobile workstations where power efficiency and thermal management are critical. While its benchmark scores are far lower, it is not a weak GPU; its 85th percentile ranking shows it is competitive with parts like the AMD Radeon RX 6800 XT and surpasses the RX 6550M. Users requiring a capable GPU for a laptop should consider the A1000 Mobile, but they must accept a significant performance compromise compared to the desktop-class 4070 SUPER. The choice is not about which is better, but which is better suited to the constraints of the system. Desktop users should pick the 4070 SUPER without hesitation, while laptop users have no choice but to consider the A1000 Mobile if they need its specific power profile.
