The recorded data shows a decisive performance advantage for the NVIDIA Tesla T4 across both benchmark tests. In Geekbench OpenCL, the Tesla T4 scores 61,276 points against the RTX A1000 Mobile's 48,703 points, a 25.8% delta in favor of the Tesla T4. The gap widens considerably in Geekbench Vulkan, where the Tesla T4 reaches 72,190 points while the RTX A1000 Mobile manages 46,782, resulting in a 54.3% lead for the Tesla T4. These are not marginal differences; the Vulkan result particularly highlights how the Tesla T4 excels in compute-heavy workloads.

The Tesla T4's average benchmark score of 66,733 places it at the 90th percentile of all GPUs, while the RTX A1000 Mobile's 47,743 average sits at the 85th percentile. That 5-percentile gap may sound modest, but the raw score difference of 18,990 points (39.8% higher for the Tesla T4) tells a more emphatic story. In the head-to-head comparison, the Tesla T4 wins both tests, giving it a 2-0 sweep, with no benchmark where the RTX A1000 Mobile emerges ahead.

Context from the nearest-rival data reinforces the Tesla T4's standing. Its average score of 66,733 is 1.1% above the AMD Radeon VII (66,004) and 2.5% above the NVIDIA Tesla P40 (65,095). It trails the AMD Radeon Instinct MI25 (68,562) by 2.7% and the Intel Arc A770 (68,809) by 3%. The RTX A1000 Mobile, meanwhile, sits in a lower bracket: its 47,743 average is 1.5% below the AMD Radeon RX 6800 XT (48,477), though it edges past the AMD Radeon RX 6550M (46,702) by 2.2%, the Intel Arc A530M (46,614) by 2.4%, and the AMD Radeon RX 5600M (46,601) by 2.5%. In essence, the Tesla T4 competes with desktop-class accelerators from 2018-2019, while the RTX A1000 Mobile aligns with mid-range mobile GPUs from the same era.

The Vulkan delta of 54.3% is the standout figure. It suggests the Tesla T4's architecture handles the Vulkan API's compute and rendering paths with far greater efficiency relative to the RTX A1000 Mobile. The OpenCL delta of 25.8%, while smaller, still represents a substantial margin. Both tests point in the same direction: the Tesla T4 is the stronger compute performer by a wide margin, and no benchmark in the database flips that conclusion.

The Verdict

The data is unambiguous. The NVIDIA Tesla T4 wins every recorded benchmark against the RTX A1000 Mobile, and it does so by margins that range from 25.8% to 54.3%. For any workload measured by Geekbench OpenCL or Vulkan, the Tesla T4 is the superior choice. Its 90th-percentile ranking versus the RTX A1000 Mobile's 85th-percentile ranking reinforces this, as does its average score of 66,733, which is nearly 40% higher than the 47,743 average of the RTX A1000 Mobile.

Who should pick the Tesla T4? Anyone prioritizing raw compute throughput, particularly in Vulkan scenarios, will find the 54.3% advantage decisive. The Tesla T4 also offers 16 GB of GDDR6 memory against the RTX A1000 Mobile's 4 GB, a fourfold capacity difference that matters for large datasets or high-resolution textures. Its 320.0 GB/s memory bandwidth versus 176.0 GB/s further cements its lead in memory-bound tasks. The Tesla T4's pixel rate of 101.8 GPixel/s and texture rate of 254.4 GTexel/s dwarf the RTX A1000 Mobile's 36.48 GPixel/s and 72.96 GTexel/s, respectively.

Who should pick the RTX A1000 Mobile? The data does not favor it in any benchmark, but its profile suggests a different use case. It draws 60 W versus the Tesla T4's 70 W, a modest power saving. It is an IGP (integrated graphics processor) with no slot width, designed for portable devices, whereas the Tesla T4 is a single-slot card with a 168 mm length. The RTX A1000 Mobile also supports PCIe 4.0 x8, double the per-lane bandwidth of the Tesla T4's PCIe 3.0 x16, though the Tesla T4's x16 lane count may compensate. For a mobile workstation where the GPU must fit inside a laptop chassis, the RTX A1000 Mobile is the only viable option; the Tesla T4 cannot be integrated into a portable device. But from a pure performance standpoint, the recorded scores leave no room for debate.

Where Each One Wins

It is an IGP with no discrete dimensions, meaning it is soldered into a laptop motherboard, while the Tesla T4 requires a 168 mm single-slot card with no display outputs. The RTX A1000 Mobile also has display outputs described as "Portable Device Dependent," allowing it to drive laptop screens, whereas the Tesla T4 has no outputs at all. Its 8 nm process node from Samsung is more advanced than the Tesla T4's 12 nm node from TSMC, leading to a higher transistor density of 43.5M per mm² versus 25.0M per mm². The RTX A1000 Mobile's base clock of 630 MHz is higher than the Tesla T4's 585 MHz, though the Tesla T4's boost clock of 1590 MHz far exceeds the RTX A1000 Mobile's 1140 MHz.

In terms of nearest-rival positioning, the Tesla T4 sits among desktop accelerators like the Radeon VII and Tesla P40, while the RTX A1000 Mobile competes with mobile parts like the RX 6550M and Arc A530M. That placement alone tells you which GPU belongs in a server rack versus a thin-and-light laptop.
