NVIDIA Tesla C2070 vs NVIDIA TITAN V CEO Edition Comparison

FAQ

Q: How do the two GPUs compare in raw compute performance?

A: The NVIDIA TITAN V CEO Edition delivers 14.90 TFLOPS of FP32 compute versus the Tesla C2070’s 1,027.7 GFLOPS (approximately 1.03 TFLOPS). This represents a massive generational leap, with the TITAN V CEO Edition offering roughly 14.5x the single-precision throughput.

Q: What are the memory specifications of each card?

A: The Tesla C2070 features 6 GB of GDDR5 on a 384-bit bus, yielding 143.4 GB/s bandwidth. The TITAN V CEO Edition ships with 32 GB of HBM2 on a 4096-bit bus, providing 868.4 GB/s of bandwidth — over 6x more memory capacity and roughly 6x higher bandwidth.

Q: Which card has better benchmark scores?

A: The Tesla C2070’s only benchmark result is a Geekbench OpenCL score of 9,716, while the TITAN V CEO Edition scores 16,988 in Passmark G3D and 1,086 in Passmark G2D. However, the TITAN V CEO Edition’s average benchmark score is 9,037, which is lower than the Tesla C2070’s 9,716 average, due to the inclusion of its lower 2D score in the average calculation.

Q: How do the cards compare in transistor density?

A: The Tesla C2070 uses a 40 nm process with 3,100 million transistors on a 529 mm² die, giving a density of 5.9M transistors per mm². The TITAN V CEO Edition uses a 12 nm process with 21,100 million transistors on an 815 mm² die, achieving 25.9M transistors per mm² — a density roughly 4.4x higher.

Q: What API support differs between the two?

A: Both support DirectX 12 and OpenGL 4.6, but the Tesla C2070 is limited to DirectX 12 (11_0) while the TITAN V CEO Edition supports DirectX 12 (12_1). Additionally, the TITAN V CEO Edition supports Vulkan 1.4, whereas the Tesla C2070 has no Vulkan support listed.

Q: What are the power and cooling requirements?

A: The Tesla C2070 has a TDP of 238 W and requires a 550 W power supply, while the TITAN V CEO Edition has a TDP of 250 W and requires a 600 W power supply. Both are dual-slot cards with 1x 6-pin + 1x 8-pin power connectors.

Architecture Differences

The two NVIDIA GPUs represent entirely different architectural generations. The Tesla C2070 is built on the Fermi architecture with the GF100 chip, fabricated on TSMC’s 40 nm process. It packs 3,100 million transistors into a 529 mm² die, yielding a modest 5.9M transistors per mm². The TITAN V CEO Edition, by contrast, uses the Volta architecture with the GV100 chip, manufactured on a 12 nm process. It integrates 21,100 million transistors — nearly 7x more — into an 815 mm² die, achieving a transistor density of 25.9M per mm².

The compute core configurations differ dramatically. The Tesla C2070 has 448 shading units, 56 texture mapping units, and 48 ROPs. The TITAN V CEO Edition vastly increases these counts to 5,120 shading units, 320 TMUs, and 128 ROPs. The Volta card also includes 640 tensor cores, a feature absent from the Fermi-based Tesla. This architectural addition enables dedicated tensor operations, though the benchmark data does not isolate their performance impact.

Memory architecture is another fundamental divergence. The Tesla C2070 uses 6 GB of GDDR5 on a 384-bit bus, while the TITAN V CEO Edition employs 32 GB of HBM2 on a 4096-bit bus. The HBM2 implementation provides a 6x wider memory interface and correspondingly higher bandwidth. Pixel and texture fill rates reflect the architectural gap: the Tesla achieves 16.07 GPixel/s and 32.14 GTexel/s, while the TITAN V CEO Edition reaches 186.2 GPixel/s and 465.6 GTexel/s — roughly 11.6x and 14.5x higher, respectively.

Clock behavior also differs. The Tesla C2070 lists no base or boost clock, only a memory clock of 747 MHz (3 Gbps effective). The TITAN V CEO Edition has a base clock of 1200 MHz, boost clock of 1455 MHz, and a memory clock of 848 MHz (1696 Mbps effective). The TITAN V CEO Edition also supports FP16 compute at 29.80 TFLOPS (2:1 ratio), a capability entirely absent from the Tesla C2070’s specifications.

Head-to-Head Benchmarks

Direct head-to-head benchmark comparisons between these two cards are not available in the data. However, their individual benchmark scores and nearest rival comparisons provide useful context.

The Tesla C2070’s Geekbench OpenCL score of 9,716 places it in the 47th percentile of all GPUs. Its nearest rivals include the NVIDIA Tesla M10 (avg score 9,724, delta -0.1%), NVIDIA Quadro P4000 (avg score 9,665, delta 0.5%), AMD Radeon Pro WX 2100 (avg score 9,653, delta 0.7%), and NVIDIA GeForce GTX 1070 (avg score 9,780, delta -0.7%). This clustering indicates the Tesla C2070 performs essentially at parity with these mid-range cards from later generations, with deltas under 1% in all cases.

The TITAN V CEO Edition presents a contrasting picture. Its Passmark G3D score is 16,988, but its Passmark G2D score is only 1,086. The average of these two tests yields 9,037, placing the card in the 45th percentile of all GPUs. Its nearest rivals include the NVIDIA GeForce GTX 660 (avg score 9,022, delta 0.2%), NVIDIA GeForce GTX 560 (avg score 9,058, delta -0.2%), AMD Radeon 550X (avg score 8,918, delta 1.3%), and AMD Radeon 890M (avg score 9,210, delta -1.9%). The fact that a high-end Volta card sits alongside cards like the GTX 660 and Radeon 550X in average score is explained by its very low 2D benchmark result dragging down the aggregate.

The data shows no direct matchups between the two cards in any shared benchmark. The Tesla C2070 only has a Geekbench result, while the TITAN V CEO Edition only has Passmark results. Consequently, a direct score-to-score comparison is impossible from the available facts. What is clear is that the TITAN V CEO Edition’s 3D score of 16,988 is far higher than the Tesla C2070’s 9,716 Geekbench score, though different benchmark suites make direct numerical comparison unreliable. The percentile rankings — 47th for the Tesla versus 45th for the TITAN V CEO Edition — suggest that, despite its massive architectural advantages, the TITAN V CEO Edition’s average benchmark performance does not rank higher, due to the 2D score penalty.

Where Each One Wins

The Tesla C2070 wins in the category of average benchmark score, with 9,716 versus the TITAN V CEO Edition’s 9,037. This is a counterintuitive result driven by benchmark methodology: the Tesla has a single Geekbench OpenCL score, while the TITAN V CEO Edition’s average includes a low Passmark G2D score of 1,086 that pulls its average down. The Tesla also carries a higher percentile ranking (47th vs 45th), a lower TDP (238 W vs 250 W), a more compact length (248 mm vs 267 mm), and an earlier release date.

The TITAN V CEO Edition wins decisively in nearly every raw performance metric. Its FP32 compute of 14.90 TFLOPS dwarfs the Tesla’s 1,027.7 GFLOPS. Its memory bandwidth of 868.4 GB/s is over 6x the Tesla’s 143.4 GB/s, and its 32 GB memory capacity is more than 5x larger. The TITAN V CEO Edition’s shading unit count (5,120 vs 448), TMU count (320 vs 56), and ROP count (128 vs 48) are all dramatically higher. It also offers tensor cores, FP16 support, Vulkan 1.4, PCIe 3.0, and modern display outputs including HDMI 2.0 and DisplayPort 1.4a.

For workload suitability, the Tesla C2070’s profile suggests it remains competitive in compute tasks that rely on OpenCL performance, as evidenced by its Geekbench score matching cards like the GTX 1070 within 0.7%. Its lower power draw and shorter length make it easier to fit into space-constrained systems. The TITAN V CEO Edition, with its massive memory pool, high bandwidth, and tensor core support, is positioned for memory-intensive and modern compute workloads. Its Passmark G3D score of 16,988 indicates strong 3D rendering capability, though its 2D performance is notably weak.

In practical terms, the data shows the Tesla C2070 is a Fermi-era compute card that still holds its own against much newer mid-range GPUs in OpenCL workloads. The TITAN V CEO Edition is a Volta flagship whose average benchmark score is dragged down by its 2D result, but whose architectural specifications — 21,100 million transistors, 640 tensor cores, 868.4 GB/s bandwidth — place it in a different performance class for compute-heavy applications.
