NVIDIA T1000 vs NVIDIA T1000 8 GB Comparison

NVIDIA’s T1000 and T1000 8 GB are nearly identical twins, sharing the same TU117 chip, the same 12 nm Turing architecture, and the same core configuration. The data shows that the only meaningful difference between them is memory capacity: 4 GB on the standard model versus 8 GB on the 8 GB variant. In raw compute performance, the T1000 leads the 8 GB model by a razor-thin 0.9% in the only shared benchmark, but the 8 GB version’s extra memory positions it for workloads where capacity trumps clock-for-clock speed. This is not a generational leap; it is a memory-focused revision of a single product.

Where Each One Wins

The standard NVIDIA T1000 wins on raw benchmark performance. In the Geekbench Vulkan test, the T1000 scores 34,874, while the T1000 8 GB scores 34,561. That is a 0.9% delta, a margin that falls within run-to-run variance but still counts as a win in the head-to-head data. The T1000 also holds a higher average benchmark score of 36,289 across its two recorded tests (Geekbench OpenCL at 37,704 and Geekbench Vulkan at 34,874), compared to the 8 GB model’s single-test average of 34,561. The standard card’s 80th percentile ranking versus all GPUs edges out the 8 GB model’s 79th percentile.

The T1000 8 GB wins on capacity, and that is its entire case. With 8 GB of GDDR6 memory versus 4 GB, it can hold larger datasets, bigger textures, or more concurrent GPU contexts before hitting memory limits. The bandwidth is identical at 160.0 GB/s, so the extra memory does not speed up data movement; it just allows more data to reside on the card. For workloads that spill over 4 GB—such as larger machine learning inference batches, complex CAD assemblies, or multi-application rendering pipelines—the 8 GB version avoids the fallback to system memory, which is often a severe performance penalty.

Architecture Differences

The two cards share the same TU117 chip, manufactured on a 12 nm process at TSMC, with 4,700 million transistors on a 200 mm² die. Transistor density is identical at 23.5M per mm². Both feature 896 shading units, 56 texture mapping units, and 32 ROPs. Neither has dedicated ray tracing cores or tensor cores; this is pure Turing graphics compute. The base clock is 1,065 MHz and the boost clock is 1,395 MHz on both cards. Memory runs at 1,250 MHz with 10 Gbps effective data rate, over a 128-bit bus, yielding 160.0 GB/s bandwidth.

The sole architectural divergence is memory size: 4 GB on the T1000, 8 GB on the T1000 8 GB. Everything else—pixel rate at 44.64 GPixel/s, texture rate at 78.12 GTexel/s, FP32 at 2.500 TFLOPS, FP16 at 5.000 TFLOPS (2:1)—is numerically identical. The TDP is 50 W for both, with no power connectors required and a suggested 250 W PSU. Both are single-slot cards measuring 156 mm in length and 69 mm in height, with 4x mini-DisplayPort 1.4a outputs. API support is the same: DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. PCIe interface is 3.0 x16 for both.

The Verdict

Pick the standard NVIDIA T1000 if your priority is the absolute highest benchmark score in a head-to-head comparison. The data shows it wins the only shared test, Geekbench Vulkan, by 0.9% (34,874 vs 34,561). It also has a higher average benchmark score (36,289 vs 34,561) and a higher percentile ranking (80th vs 79th). For users who run applications that never approach 4 GB of memory usage, the standard card offers slightly better measured performance with no downside.

Pick the NVIDIA T1000 8 GB if your workload is memory-bound. The extra 4 GB doubles the frame buffer, which is critical for tasks that exceed 4 GB. The identical 160.0 GB/s bandwidth means the additional memory does not increase throughput, but it prevents capacity-related stalling. The 8 GB model’s nearest rivals include the NVIDIA TITAN V (deltaPct 0.6) and the NVIDIA RTX A1000 (deltaPct 1), placing it in the same performance class despite the larger memory. For rendering, large-texture workloads, or running multiple GPU-accelerated applications simultaneously, the 8 GB variant is the safer choice.

The verdict is not about which is faster—it is about which fits the task. The standard T1000 edges ahead in synthetic benchmarks; the 8 GB model wins in scenarios where memory capacity is the bottleneck.

FAQ

Q: Which card has higher raw performance?

A: The standard NVIDIA T1000. In Geekbench Vulkan, it scores 34,874 versus 34,561 for the T1000 8 GB, a 0.9% advantage. Its average benchmark score is 36,289, compared to 34,561 for the 8 GB model.

Q: Is the 8 GB model better for large datasets?

A: Yes. The T1000 8 GB has 8 GB of GDDR6 memory versus 4 GB on the standard model. Both run at 160.0 GB/s bandwidth, so the benefit is purely capacity, allowing larger working sets without exceeding memory limits.

Q: Are the clock speeds different between the two?

A: No. Both cards have a base clock of 1,065 MHz and a boost clock of 1,395 MHz. Memory clock is also identical at 1,250 MHz with 10 Gbps effective data rate.

Q: Do these cards support ray tracing or tensor cores?

A: No. Both are based on the TU117 chip with 896 shading units, 56 TMUs, and 32 ROPs. They have no dedicated ray tracing cores or tensor cores.

Q: How do these cards compare to their nearest rivals?

A: The standard T1000 is 0.7% behind the AMD Radeon RX 5300M and 1.2% ahead of the AMD Radeon Pro Duo. The T1000 8 GB is 0.4% behind the NVIDIA A2 and 1% ahead of the NVIDIA RTX A1000.

Head-to-Head Benchmarks

The only direct benchmark comparison available is Geekbench Vulkan. The standard T1000 scores 34,874, and the T1000 8 GB scores 34,561. The standard card wins by 0.9%. This margin is small enough that it could be considered a tie in real-world use, but the data records it as a win for the T1000.

Looking at the broader benchmark picture, the standard T1000 also has a Geekbench OpenCL score of 37,704, which is higher than its own Vulkan score and far above the 8 GB model’s only recorded score of 34,561. The standard card’s average benchmark score of 36,289 reflects the OpenCL result pulling the average up. The 8 GB model has no OpenCL score in the data, so its average is just the Vulkan number.

The nearest rival data further contextualizes these scores. The standard T1000 sits within 2.2% of four rivals: the AMD Radeon RX 5300M (deltaPct -0.7), NVIDIA GeForce GTX TITAN X (deltaPct -0.7), AMD Radeon Pro Duo (deltaPct 1.2), and NVIDIA Quadro GV100 (deltaPct 2.2). The 8 GB model’s rivals are similar in score: AMD Radeon HD 7970 (deltaPct 0.1), NVIDIA A2 (deltaPct -0.4), NVIDIA TITAN V (deltaPct 0.6), and NVIDIA RTX A1000 (deltaPct 1). This places both cards in the same performance tier, with the standard T1000 holding a marginal edge.
