AMD Radeon RX 6800 vs NVIDIA T1000 8 GB Comparison

Where Each One Wins

The benchmark database records a single shared test between the NVIDIA T1000 8 GB and the AMD Radeon RX 6800: Geekbench Vulkan. In that test, the AMD Radeon RX 6800 is the clear winner, posting a score of 115,107 against the NVIDIA T1000 8 GB's 34,561. That is a 70% gap in favor of AMD, a decisive margin that defines the use-case split between these two cards.

For compute-heavy workloads that rely on the Vulkan API, the AMD Radeon RX 6800 is the superior choice. Its raw score is more than three times higher, indicating that the card can handle far more demanding parallel workloads. The NVIDIA T1000 8 GB, by contrast, sits in a much lower performance tier. Its average benchmark score of 34,561 places it in the 79th percentile of all GPUs in the database, which is actually higher than the AMD card's 75th percentile, despite the AMD card's vastly superior raw score in this single test. This is because the AMD card's average across its broader benchmark suite (30,095) is dragged down by weaker results in older DirectX tests, while the NVIDIA card's single recorded result is its only data point.

So the use-case split is straightforward: if the workload is Vulkan-based and demands high throughput, the RX 6800 wins outright. If the workload is lighter, or if the application does not heavily stress the GPU, the T1000's lower power draw and compact size may be more relevant, but from a pure performance standpoint, the AMD card wins the only directly comparable test.

Head-to-Head Benchmarks

The only direct comparison in the database is the Geekbench Vulkan test, and the result is lopsided. The AMD Radeon RX 6800 scores 115,107, while the NVIDIA T1000 8 GB scores 34,561. The delta is 70% in favor of AMD. To put that in context, the T1000's score is nearly identical to its nearest rival, the AMD Radeon HD 7970 (34,541), which is just 0.1% behind. The RX 6800, meanwhile, sits in a completely different performance class, closer to the NVIDIA GeForce RTX 3070 Ti (29,945) and RTX 2080 Ti (29,783) in its average score, though its Vulkan result is far above those averages.

The magnitude of this Vulkan gap is not surprising given the underlying hardware. The RX 6800 has 3,840 shading units versus 896 on the T1000, and its boost clock of 2105 MHz is substantially higher than the T1000's 1395 MHz. The FP32 throughput tells the story: 16.17 TFLOPS for the AMD card versus 2.500 TFLOPS for the NVIDIA card. That is roughly 6.5x the raw compute, and while the Vulkan test does not scale perfectly with FP32, the 70% gap in the recorded score reflects a massive difference in execution capacity.

Beyond the single head-to-head, the database shows the RX 6800's broader benchmark profile. It scores 153,635 in Geekbench Metal, 24,508 in Geekbench OpenCL, and 22,067 in Passmark G3D. Its Passmark compute score is 10,864. The T1000 has no other recorded benchmarks, so its average score equals its Vulkan result. This means the T1000's 79th percentile ranking is based on a single data point, while the RX 6800's 75th percentile reflects an average of 11 tests. The data suggests the RX 6800 is a high-performance card with some weaker legacy DirectX results, not a uniformly dominant one.

Specification Differences

The two cards differ in nearly every major specification. The NVIDIA T1000 8 GB uses a 12 nm process, while the AMD Radeon RX 6800 uses a 7 nm process, both from TSMC. The transistor counts are starkly different: 4,700 million for the T1000 versus 26,800 million for the RX 6800. Die size also differs, at 200 mm² versus 520 mm². The transistor density is 23.5M per mm² for NVIDIA and 51.5M per mm² for AMD.

Memory configurations are different in both capacity and bandwidth. The T1000 has 8 GB of GDDR6 on a 128-bit bus, yielding 160.0 GB/s. The RX 6800 has 16 GB of GDDR6 on a 256-bit bus, yielding 512.0 GB/s. Clock speeds are higher on the AMD card: base 1700 MHz versus 1065 MHz, boost 2105 MHz versus 1395 MHz. The RX 6800 also has a "game" clock of 1815 MHz, which the T1000 does not list.

The compute units scale accordingly. The RX 6800 has 3,840 shading units, 240 texture mapping units, and 96 ROPs. The T1000 has 896 shading units, 56 TMUs, and 32 ROPs. The AMD card also has 60 ray tracing cores, while the T1000 has none. Pixel rate and texture rate are far higher on AMD: 202.1 GPixel/s versus 44.64 GPixel/s, and 505.2 GTexel/s versus 78.12 GTexel/s.

Power and physical characteristics diverge sharply. The T1000 is a single-slot card with no power connectors and a 50 W TDP. The RX 6800 is a dual-slot card with two 8-pin connectors and a 250 W TDP. The suggested PSU is 250 W for the T1000 and 600 W for the RX 6800. The T1000 is 156 mm long and 69 mm high, while the RX 6800 is 267 mm long, 120 mm high, and 40 mm wide. The bus interface also differs: PCIe 3.0 x16 on the T1000 versus PCIe 4.0 x16 on the RX 6800. Display outputs are different as well, with the T1000 offering four mini-DisplayPort 1.4a connectors, while the RX 6800 offers one HDMI 2.1, two DisplayPort 1.4a, and one USB Type-C.

Architecture Differences

The NVIDIA T1000 8 GB is built on the Turing architecture, using the TU117 chip. It is part of the Quadro Turing generation, succeeding Quadro Volta and preceding Workstation Ampere. The architecture is a 12 nm design with no dedicated ray tracing or tensor cores. Its FP16 performance is 5.000 TFLOPS with a 2:1 ratio, meaning half the FP32 rate. The card supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4.

The AMD Radeon RX 6800 is built on RDNA 2.0, using the Navi 21 chip. It belongs to the Navi II (RX 6000) generation, succeeding Navi and preceding Navi III. The 7 nm design includes 60 ray tracing cores, a key architectural addition that the T1000 lacks. Its FP16 performance is 32.33 TFLOPS with a 2:1 ratio, again half of FP32. It supports DirectX 12 Ultimate (12_2), which includes ray tracing features, along with OpenGL 4.6 and Vulkan 1.4.

The architectural differences explain the performance gap. RDNA 2 is designed for high-throughput gaming and compute, with a wider memory bus and more execution units. Turing's TU117 is a low-power workstation chip optimized for efficiency and compactness, not raw throughput. The process node difference (7 nm versus 12 nm) also contributes to the RX 6800's higher clocks and lower power efficiency per transistor, though the T1000's 50 W TDP is far lower in absolute terms.

The RX 6800's memory subsystem is architecturally superior as well, with a 256-bit bus and 512.0 GB/s bandwidth. The T1000's 128-bit bus and 160.0 GB/s are adequate for its intended workload but cannot match the AMD card's bandwidth for large data sets. The presence of ray tracing cores on the RX 6800 also means it can handle DirectX 12 Ultimate workloads that the T1000 cannot, though this is not directly measured in the shared benchmark.

The Verdict

The recorded data points to a single conclusion: the AMD Radeon RX 6800 is the far more powerful GPU in the only directly comparable test. Its Geekbench Vulkan score of 115,107 is 70% higher than the NVIDIA T1000 8 GB's 34,561. The RX 6800 also has higher memory capacity (16 GB versus 8 GB), higher bandwidth (512.0 GB/s versus 160.0 GB/s), and vastly more compute units (3,840 versus 896 shading units). Its FP32 throughput of 16.17 TFLOPS dwarfs the T1000's 2.500 TFLOPS.

However, the T1000 8 GB is not without its own strengths in the database. It has a higher percentile ranking (79th versus 75th), though this is based on a single benchmark. Its power draw is dramatically lower: 50 W versus 250 W, with no power connectors required and a 250 W suggested PSU versus 600 W. Its single-slot design and compact dimensions (156 mm length, 69 mm height) make it suitable for space-constrained systems. The T1000 also has a lower transistor count and die size, which may indicate lower manufacturing complexity, though this is not directly a performance metric.

For anyone choosing between these two based on the database, the decision hinges on workload. If the task is Vulkan-based compute or gaming, the RX 6800 is the only rational choice. If the task is light workstation duty where power and space are paramount, the T1000 may suffice, but it will deliver a fraction of the performance. The data does not support the T1000 in any scenario where raw throughput matters. The RX 6800's nearest rivals in the database, such as the RTX 3070 Ti and RTX 2080 Ti, are all within 1% of its average score, confirming its position as a high-end card. The T1000's nearest rivals, including the HD 7970 and A2, are all within 1% of its score, confirming its position as a low-end card. There is no overlap in performance class. The verdict is clear: pick the RX 6800 for performance, pick the T1000 only if its minimal power and size requirements are the overriding constraints.
