GPU Comparison

Head-to-Head Benchmarks

The recorded data shows a single direct comparison between the NVIDIA Tesla M4 and the NVIDIA GeForce GTX 770 in the Geekbench OpenCL test. The Tesla M4 wins decisively, scoring 16932 against the GTX 770's 15707, a margin of 7.8%. This is the only head-to-head benchmark available in the database, so the overall win tally stands at 1 for the Tesla M4 and 0 for the GTX 770.

Looking at the broader database context, the Tesla M4's OpenCL score places it in the 60th percentile among all GPUs, while the GTX 770's average benchmark score (derived from its OpenCL, Metal, and Vulkan results) sits in the 57th percentile. The Tesla M4's single score of 16932 is notably higher than the GTX 770's average of 14747 across all its benchmarks. However, the GTX 770 shows strength in specific API tests: its Vulkan score of 19166 is its best recorded result, and its Metal score of 9369 demonstrates capability in Apple-centric workloads.

The nearest rivals for the Tesla M4 in the database include the AMD Radeon HD 7970M (avg score 17019, 0.5% higher), the NVIDIA GeForce GTX 690 (avg score 17037, 0.6% higher), and the AMD Radeon RX 7600 XT (avg score 17083, 0.9% higher). The Tesla M4 trails these by less than 1%, placing it in a tightly contested performance band. The NVIDIA T400 4 GB sits just below with an average score of 16792, which the Tesla M4 beats by 0.8%. For the GTX 770, its nearest rivals include the AMD Radeon RX 5500 XT (avg score 14692, 0.4% lower), the NVIDIA Quadro M2000 (avg score 14532, 1.5% lower), and the NVIDIA GeForce GTX 660 Ti (avg score 15063, 2.1% higher). The AMD Radeon Pro 560X also edges it out by 2.2% with an average score of 15082.

The 7.8% OpenCL advantage for the Tesla M4 is meaningful, but the GTX 770's Vulkan score of 19166 suggests that in Vulkan-based workloads, the GTX 770 could potentially outperform the Tesla M4, though no direct comparison exists in the data. The database records only the OpenCL head-to-head, so conclusions about other APIs remain speculative.

Architecture Differences

The two cards come from different NVIDIA architectures. The Tesla M4 uses the GM206 chip built on the Maxwell 2.0 architecture, while the GTX 770 uses the GK104 chip on the older Kepler architecture. Both are manufactured on a 28 nm process at TSMC, but the transistor counts differ: the Tesla M4 has 2,940 million transistors on a 228 mm² die, yielding a density of 12.9 million transistors per mm². The GTX 770 packs 3,540 million transistors on a larger 294 mm² die, with a slightly lower density of 12.0 million per mm².

The memory subsystems are markedly different. The Tesla M4 features 4 GB of GDDR5 on a 128-bit bus, delivering 88.00 GB/s of bandwidth. The GTX 770 has 2 GB of GDDR5 on a 256-bit bus, achieving 224.4 GB/s. Despite having half the VRAM capacity, the GTX 770's wider bus gives it more than double the memory bandwidth.

Compute resources also diverge. The Tesla M4 has 1,024 shading units, 64 TMUs, and 32 ROPs. The GTX 770 has 1,536 shading units, 128 TMUs, and 32 ROPs. This gives the GTX 770 higher pixel rate (34.72 GPixel/s vs 34.30 GPixel/s) and significantly higher texture rate (138.9 GTexel/s vs 68.61 GTexel/s). FP32 performance is also higher on the GTX 770 at 3.333 TFLOPS versus 2.195 TFLOPS. Neither card has RT cores or tensor cores.

API support differs in DirectX and Vulkan versions. The Tesla M4 supports DirectX 12 (12_1) and Vulkan 1.4, while the GTX 770 supports DirectX 12 (11_0) and Vulkan 1.2.175. Both support OpenGL 4.6. The Tesla M4 has no display outputs, while the GTX 770 has 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2.

Power characteristics are starkly different. The Tesla M4 has a TDP of 50 W and a suggested PSU of 250 W, while the GTX 770 has a TDP of 230 W and a suggested PSU of 550 W. The GTX 770 is dual-slot with 1x 6-pin and 1x 8-pin power connectors; the Tesla M4 is single-slot with no power connectors listed. Physical dimensions are recorded only for the GTX 770: 267 mm length, 111 mm height, and 38 mm width.

The Verdict

Based on the recorded data, the NVIDIA Tesla M4 is the stronger choice for compute-oriented OpenCL workloads, winning the only direct benchmark by 7.8%. Its higher percentile ranking (60th vs 57th) and superior average score (16932 vs 14747) reinforce this conclusion. However, the GTX 770's Vulkan score of 19166 indicates that in Vulkan-specific tasks, it may be the better performer, though no direct comparison exists.

The Tesla M4 also offers a massive efficiency advantage: 50 W TDP versus 230 W, with a suggested PSU of 250 W versus 550 W. For systems with power constraints or limited cooling, the Tesla M4 is clearly preferable. Its single-slot design and lack of display outputs suggest it is intended for server or compute environments, while the GTX 770's display outputs and dual-slot design target desktop graphics.

The GTX 770's higher memory bandwidth (224.4 GB/s vs 88.00 GB/s) and larger shading unit count (1,536 vs 1,024) suggest it may excel in memory-intensive or shader-heavy scenarios, but the benchmark data does not confirm this in the OpenCL test. The Tesla M4's 4 GB VRAM versus 2 GB may be an advantage for larger datasets, despite the lower bandwidth.

The GTX 770 has a recorded launch MSRP of 399 USD; the Tesla M4 has no launch MSRP in the database.

Where Each One Wins

The Tesla M4 wins in the only recorded head-to-head benchmark, the Geekbench OpenCL test, by 7.8%. It also wins on power efficiency, with a 50 W TDP versus 230 W, and on VRAM capacity, with 4 GB versus 2 GB. Its higher Vulkan API version (1.4 vs 1.2.175) and DirectX 12_1 support (versus 11_0) give it a forward-looking feature set. The single-slot design and absence of power connectors make it suitable for dense compute environments with limited space and power budgets. Its higher percentile ranking (60th vs 57th) and average score (16932 vs 14747) indicate it is generally the better performer in the database's measured workloads.

The GTX 770 wins on raw computational resources: higher FP32 throughput (3.333 TFLOPS vs 2.195 TFLOPS), double the texture rate (138.9 GTexel/s vs 68.61 GTexel/s), more shading units (1,536 vs 1,024), and more TMUs (128 vs 64). Its memory bandwidth of 224.4 GB/s is more than double the Tesla M4's, which could benefit bandwidth-bound tasks. The GTX 770 also has display outputs, making it usable for traditional desktop graphics, whereas the Tesla M4 has none. Its Vulkan score of 19166 is the highest recorded benchmark among both cards, suggesting Vulkan-specific workloads may favor the GTX 770 despite the OpenCL loss. The GTX 770's dimensions are recorded (267 mm length, 111 mm height, 38 mm width), while the Tesla M4's are not, which may matter for case compatibility.

For compute workloads using OpenCL, the Tesla M4 is the winner. For scenarios requiring high memory bandwidth, extensive shader resources, or display output, the GTX 770 holds advantages, though these are not directly validated by the head-to-head data. The overall benchmark tally favors the Tesla M4, and the efficiency gap is substantial, but the GTX 770's specification sheet suggests it remains competitive in specific tasks that the database does not directly measure.
