AMD Radeon RX 6800M vs NVIDIA T1000 8 GB Comparison

NVIDIA T1000 8 GB and AMD Radeon RX 6800M occupy very different positions in the database, with the RX 6800M delivering a dominant performance advantage in the one directly comparable workload. The T1000 is a low-power workstation card built for stability and multi-display output, while the RX 6800M is a high-performance mobile GPU designed for demanding gaming and compute. Benchmark results show a clear hierarchy, but the architecture and specification differences explain why these two products target entirely separate use cases.

Head-to-Head Benchmarks

The only directly comparable benchmark in the database is Geekbench Vulkan, and the result is not close. The AMD Radeon RX 6800M scores 94,766 points, while the NVIDIA T1000 8 GB scores 34,561 points. That translates to a 63.5% deficit for the T1000, meaning the RX 6800M delivers roughly 2.7 times the Vulkan performance of the NVIDIA card. This is the largest margin recorded in the head-to-head comparison, and it reflects fundamental differences in raw compute throughput, memory bandwidth, and architectural design.

The RX 6800M’s performance extends beyond that single test. Its average benchmark score of 28,874 places it in the 74th percentile of all GPUs, while the T1000’s average of 34,561 lands in the 79th percentile. That said, the T1000’s percentile is higher because it has only one recorded benchmark, which is Vulkan, a workload where the RX 6800M excels. The RX 6800M’s broader benchmark suite, including DirectX 9, 10, 11, 12, OpenCL, Metal, and compute tests, shows a more complete picture of its capabilities. For example, the RX 6800M scores 13,261 in Passmark G3D and 5,032 in GPU compute, numbers that the T1000 cannot match in any comparable metric.

The nearest rivals for each card highlight their respective tiers. The T1000 sits alongside the NVIDIA A2 (34,690 points, 0.4% ahead) and the NVIDIA TITAN V (34,355 points, 0.6% behind), showing that its Vulkan score is competitive with older high-end desktop parts. The RX 6800M, by contrast, is bracketed by the AMD Radeon RX 570 (28,766 points, 0.4% behind) and the Intel Arc A370M (29,175 points, 1% ahead), suggesting it performs like a mid-range desktop GPU from a previous generation. This context makes the 63.5% gap in the head-to-head test even more pronounced.

Architecture Differences

The architectural divide between these two GPUs is stark. The T1000 uses the TU117 chip on NVIDIA’s Turing architecture, built on a 12 nm process at TSMC. The RX 6800M uses the Navi 22 chip with AMD’s RDNA 2.0 architecture, fabricated on a 7 nm process, also at TSMC. The smaller process node gives AMD a significant density advantage: the RX 6800M packs 17,200 million transistors into a 335 mm² die, yielding a transistor density of 51.3 million per mm². The T1000 has 4,700 million transistors on a 200 mm² die, for a density of 23.5 million per mm². That means the RX 6800M fits more than three times the transistors into roughly 67% more silicon area.

Core counts tell a similar story. The T1000 has 896 shading units, 56 texture mapping units, and 32 ROPs. The RX 6800M has 2,560 shading units, 160 TMUs, and 64 ROPs. That is 2.9 times more shading units, 2.9 times more TMUs, and exactly twice as many ROPs. The RX 6800M also includes 40 ray tracing cores, while the T1000 has none. Neither card has tensor cores, so AI acceleration is not a differentiator here.

Clock speeds also favor AMD. The T1000 runs at a base of 1065 MHz and boosts to 1395 MHz. The RX 6800M operates at a base of 2116 MHz, boosts to 2390 MHz, and has a game clock of 2300 MHz. Those higher clocks, combined with the larger core count, produce a massive throughput advantage. The RX 6800M delivers 12.24 TFLOPS of FP32 compute and 24.47 TFLOPS of FP16, while the T1000 manages 2.500 TFLOPS FP32 and 5.000 TFLOPS FP16. That is a 4.9 times difference in both precision formats.

Memory architecture is another major split. The T1000 has 8 GB of GDDR6 on a 128-bit bus, providing 160.0 GB/s of bandwidth. The RX 6800M has 12 GB of GDDR6 on a 192-bit bus, delivering 384.0 GB/s. The RX 6800M also runs its memory at 2000 MHz (16 Gbps effective) compared to the T1000’s 1250 MHz (10 Gbps effective). This 2.4 times bandwidth advantage is critical for high-resolution textures and compute workloads that saturate memory.

Specification Differences

The two GPUs differ in nearly every measurable specification. The T1000 uses TU117 on Turing, while the RX 6800M uses Navi 22 on RDNA 2.0. Process nodes are 12 nm versus 7 nm, and transistor counts are 4,700 million versus 17,200 million. Die size is 200 mm² versus 335 mm², with densities of 23.5M versus 51.3M per mm².

Clock speeds favor AMD across the board: base 1065 MHz versus 2116 MHz, boost 1395 MHz versus 2390 MHz. The RX 6800M also lists a game clock of 2300 MHz, which the T1000 lacks. Memory clocks are 1250 MHz (10 Gbps effective) versus 2000 MHz (16 Gbps effective). Memory size is 8 GB versus 12 GB, bus width 128-bit versus 192-bit, and bandwidth 160.0 GB/s versus 384.0 GB/s.

Compute resources differ by roughly three times: shading units 896 versus 2560, TMUs 56 versus 160, ROPs 32 versus 64. The RX 6800M adds 40 ray tracing cores. Pixel rate is 44.64 GPixel/s versus 153.0 GPixel/s, and texture rate is 78.12 GTexel/s versus 382.4 GTexel/s. FP32 throughput is 2.500 TFLOPS versus 12.24 TFLOPS, and FP16 is 5.000 TFLOPS versus 24.47 TFLOPS.

Bus interface is PCIe 3.0 x16 versus PCIe 4.0 x16. Display outputs are 4x mini-DisplayPort 1.4a versus portable device dependent. The T1000 is 156 mm long and 69 mm tall; the RX 6800M has no listed dimensions.

Where Each One Wins

The NVIDIA T1000 wins in scenarios that prioritize low power consumption and compact physical design. Its 50 W TDP is less than half of the RX 6800M’s 145 W, and it requires no auxiliary power connectors, making it suitable for systems with modest power budgets. The single-slot form factor and 156 mm length allow installation in small chassis, and the four mini-DisplayPort outputs support multi-monitor workstation setups. The T1000’s 250 W suggested PSU also makes it compatible with older or lower-capacity power supplies.

The AMD Radeon RX 6800M wins in raw performance across every compute and graphics metric. Its Vulkan score is 63.5% higher, and its FP32 throughput is nearly five times greater. The 384.0 GB/s memory bandwidth and 12 GB capacity are better suited for large datasets and high-resolution textures. The 40 ray tracing cores enable hardware-accelerated ray tracing, a feature the T1000 lacks entirely. The RX 6800M’s DirectX 12 Ultimate support and higher pixel and texture rates make it the clear choice for gaming and modern 3D workloads.

The RX 6800M also wins on architectural efficiency. The 7 nm process and higher transistor density allow it to deliver more performance per die area, even though it consumes more power. The PCIe 4.0 interface doubles the bandwidth available to the host system compared to the T1000’s PCIe 3.0, which matters for data transfer in compute tasks.

The Verdict

The data points to an unambiguous conclusion: the AMD Radeon RX 6800M is the far more powerful GPU, and the NVIDIA T1000 8 GB is the far more power-efficient and physically compact option. If the workload demands maximum frame rates, compute throughput, or ray tracing, the RX 6800M is the only rational choice. Its 94,766 Vulkan score versus 34,561 for the T1000, combined with 12.24 TFLOPS FP32 and 384.0 GB/s bandwidth, leaves no doubt about performance superiority.

The T1000 is not without merit. Its 50 W TDP, single-slot design, and four mini-DisplayPort outputs make it ideal for multi-monitor professional environments where power and space are constrained. The 8 GB memory is sufficient for desktop workstation tasks, and the 79th percentile ranking shows it holds its own against older high-end cards in Vulkan. But for any task that stresses the GPU, the RX 6800M wins outright.

The nearest rival comparisons reinforce this split. The T1000 is grouped with the NVIDIA A2 and TITAN V, both desktop or data center parts, while the RX 6800M sits near the RX 570 and Arc A370M, which are mainstream gaming or mobile parts. This placement confirms that the T1000 is a niche workstation product, while the RX 6800M is a broad-purpose performance GPU. Users should select the T1000 for low-power, multi-display workstations and the RX 6800M for gaming, rendering, or compute-intensive applications. The benchmark results offer no middle ground.
