Architecture Differences

The RX 6800 XT is built on AMD's RDNA 2.0 architecture using the Navi 21 chip, fabricated on TSMC's 7 nm process. The die contains 26,800 million transistors across a 520 mm² area, yielding a transistor density of 51.5M per mm². The T1000 uses NVIDIA's Turing architecture with the TU117 chip, also from TSMC but on a 12 nm process. It packs 4,700 million transistors on a 200 mm² die, giving a density of 23.5M per mm².

The compute resources differ dramatically. The RX 6800 XT features 4,608 shading units, 288 texture mapping units, and 128 ROPs. It also includes 72 dedicated ray tracing cores. The T1000 has 896 shading units, 56 TMUs, and 32 ROPs, with no ray tracing cores listed. Neither card has tensor cores recorded in the database.

Clock behavior also diverges. The RX 6800 XT runs a base clock of 1825 MHz, a boost of 2250 MHz, and a game clock of 2015 MHz. The T1000 operates at 1065 MHz base and 1395 MHz boost. Memory clocks show 2000 MHz (16 Gbps effective) for the AMD card versus 1250 MHz (10 Gbps effective) for the NVIDIA card.

The output configurations reflect their intended roles. The RX 6800 XT provides 1x HDMI 2.1, 2x DisplayPort 1.4a, and 1x USB Type-C. The T1000 offers 4x mini-DisplayPort 1.4a. The AMD card is dual-slot with 2x 8-pin power connectors, while the T1000 is single-slot with no power connectors required.

API support shows a generational gap. The RX 6800 XT supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The T1000 lists DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The bus interface also differs: PCIe 4.0 x16 for the AMD card versus PCIe 3.0 x16 for the NVIDIA card.

Head-to-Head Benchmarks

The database records two direct comparisons between these cards, both in Geekbench workloads. The results are lopsided in favor of the RX 6800 XT.

In Geekbench OpenCL, the RX 6800 XT scores 171,304 against the T1000's 37,704. That is a delta of 354.3%, meaning the AMD card delivers more than 4.5 times the OpenCL performance. This workload stresses general-purpose compute, where the RX 6800 XT's 20.74 TFLOPS FP32 throughput and 512.0 GB/s bandwidth provide an overwhelming advantage over the T1000's 2.500 TFLOPS and 160.0 GB/s.

In Geekbench Vulkan, the RX 6800 XT again dominates with 136,875 versus 34,874, a delta of 292.5%. Vulkan is a low-level graphics API that benefits from raw shading power and memory bandwidth. The RX 6800 XT's 4,608 shading units and 648.0 GTexel/s texture rate dwarf the T1000's 896 shading units and 78.12 GTexel/s.

The win count is two for the RX 6800 XT and zero for the T1000 in these head-to-head tests. Notably, the T1000 has no recorded results in the other benchmark suites (3DMark, PassMark, Geekbench Metal) that the RX 6800 XT has data for. The RX 6800 XT's additional scores include 3DMark Steel Nomad DX12 at 3,689, Geekbench Metal at 181,337, and PassMark G3D at 24,980.

Specification Differences

The two cards diverge on nearly every measurable specification. The RX 6800 XT uses a 7 nm process; the T1000 uses 12 nm. Transistor count is 26,800 million versus 4,700 million, a 5.7x difference. Die size is 520 mm² versus 200 mm².

Memory capacity: 16 GB versus 4 GB. Bus width: 256-bit versus 128-bit. Bandwidth: 512.0 GB/s versus 160.0 GB/s. Shading units: 4,608 versus 896. TMUs: 288 versus 56. ROPs: 128 versus 32. Ray tracing cores: 72 versus none.

Pixel rate is 288.0 GPixel/s for the AMD card versus 44.64 GPixel/s for the NVIDIA card. Texture rate is 648.0 GTexel/s versus 78.12 GTexel/s. FP32 compute is 20.74 TFLOPS versus 2.500 TFLOPS. FP16 is 41.47 TFLOPS versus 5.000 TFLOPS, both at 2:1 ratios.

TDP is 300 W versus 50 W. Slot width is dual-slot versus single-slot. Power connectors: 2x 8-pin versus none. Suggested PSU: 700 W versus 250 W. Physical dimensions: the RX 6800 XT is 267 mm long, 120 mm high, and 50 mm wide; the T1000 is 156 mm long and 69 mm high, with no width recorded.

The release dates are about seven months apart, with the RX 6800 XT first. The AMD card has a recorded launch MSRP of 649 USD; the T1000 has no launch MSRP in the database.

Where Each One Wins

The RX 6800 XT wins in every recorded benchmark category. Its strengths are most pronounced in compute-heavy workloads: OpenCL shows a 354.3% lead, and Vulkan shows a 292.5% lead. The card also holds advantages in memory bandwidth (512.0 GB/s versus 160.0 GB/s), pixel throughput (288.0 GPixel/s versus 44.64 GPixel/s), and texture rate (648.0 GTexel/s versus 78.12 GTexel/s). For gaming or rendering tasks that demand high frame rates, high resolutions, or large textures, the RX 6800 XT's 16 GB frame buffer and 4608 shading units provide substantial headroom.

The T1000's advantages are not in raw performance but in form factor and power. It is a single-slot card with a 50 W TDP and no external power connectors, making it suitable for compact workstations or systems with limited power delivery. Its 4x mini-DisplayPort outputs support multi-display professional setups. The T1000's 156 mm length and 69 mm height allow installation in small chassis where the RX 6800 XT's 267 mm length and dual-slot width would not fit.

For professional workflows that rely on NVIDIA-specific features (though not detailed in the database), the T1000's Turing architecture may offer compatibility advantages, but the recorded data shows no benchmark where the T1000 leads. The T1000's nearest rivals, including the Radeon RX 5300M and GTX TITAN X, are all within 2.2% of its average score, indicating it competes in a lower performance tier.

The Verdict

The benchmark data presents a clear hierarchy. The RX 6800 XT outperforms the T1000 by margins of 292.5% to 354.3% in the shared tests, and its average score of 48,477 places it in the 85th percentile of all GPUs, versus the T1000's 36,289 and 80th percentile.

Users who need maximum graphics compute, whether for gaming, 3D rendering, or GPU-accelerated workloads, should choose the RX 6800 XT. Its 16 GB memory, 512.0 GB/s bandwidth, and 20.74 TFLOPS FP32 throughput make it suitable for demanding applications. The 72 ray tracing cores add hardware support for ray-traced effects, a feature the T1000 lacks entirely.

Users who prioritize low power consumption, compact size, and multi-display output should consider the T1000. Its 50 W TDP requires no auxiliary power connectors, and its single-slot design fits in constrained environments. The 4x mini-DisplayPort outputs support up to four displays, which suits workstation setups.

The RX 6800 XT's end-of-life status and 649 USD launch MSRP indicate it was a high-end consumer card. The T1000's lack of a recorded MSRP and its Quadro lineage suggest it targeted professional markets where reliability and certifications matter more than raw speed.

In direct comparison, the RX 6800 XT is the superior performer by every measured metric. The T1000 serves a different purpose: efficiency and flexibility over brute force. Neither card is currently in production, so availability depends on remaining stock or the secondary market. For anyone choosing between these two based on the database records, the RX 6800 XT delivers over three times the performance in both OpenCL and Vulkan, making it the clear choice for performance-critical tasks.
