Architecture Differences

The two GPUs come from different architectural generations. The GTX TITAN BLACK uses the GK110B chip on the Kepler architecture, built on a 28 nm process at TSMC. The MX330 uses the GP108B chip on the Pascal architecture, built on a 14 nm process at Samsung. This process difference is significant: the MX330 crams 24.3 million transistors per square millimeter, while the TITAN BLACK manages 12.6 million per square millimeter.

Raw transistor counts tell a different story. The TITAN BLACK packs 7,080 million transistors on a 561 mm² die. The MX330 has 1,800 million transistors on a 74 mm² die. So the TITAN BLACK has nearly four times the total transistors, but the MX330 has roughly double the transistor density due to the smaller process node.

Compute resources differ massively. The TITAN BLACK has 2880 shading units, 240 texture mapping units, and 48 ROPs. The MX330 has 384 shading units, 24 TMUs, and 16 ROPs. That is a 7.5x difference in shading units and a 10x difference in TMUs. Neither GPU has dedicated ray tracing or tensor cores.

Clock speeds favor the newer chip. The MX330 runs at a base of 1531 MHz and boosts to 1594 MHz. The TITAN BLACK runs at a base of 889 MHz and boosts to 980 MHz. The MX330's clocks are roughly 70% higher at base, but the TITAN BLACK's much larger compute array more than compensates.

Memory architecture is another major split. The TITAN BLACK uses 6 GB of GDDR5 on a 384-bit bus, delivering 336.0 GB/s. The MX330 uses 2 GB of GDDR5 on a 64-bit bus, delivering 56.06 GB/s. The TITAN BLACK has six times the memory bandwidth. Both list 7 Gbps effective memory speed.

Power and physical design diverge sharply. The TITAN BLACK draws 250 W, uses a dual-slot cooler, requires one 6-pin and one 8-pin power connector, and suggests a 600 W PSU. The MX330 draws 10 W, is an IGP (integrated graphics package), needs no power connectors, and has no suggested PSU. The TITAN BLACK measures 267 mm long, 111 mm tall, and 38 mm wide; the MX330 has no recorded dimensions because it is designed for portable devices.

The bus interface also differs: PCIe 3.0 x16 for the TITAN BLACK versus PCIe 3.0 x4 for the MX330. Display outputs are full desktop connectivity on the TITAN BLACK (2x DVI, 1x HDMI 1.4a, 1x DisplayPort 1.2), while the MX330 is marked as "Portable Device Dependent."

The Verdict

The data points to a clear performance hierarchy. The GTX TITAN BLACK wins both recorded head-to-head benchmarks and holds a 12.0% higher average score. Its nearest rivals are desktop and mobile discrete GPUs like the GTX 760 and Quadro K5000, which sit within 1.8% of its average score. The MX330's nearest rivals are similarly positioned, but at a lower absolute level: the Radeon HD 8870M, Radeon 880M, GTX 675MX, and Intel Arc A380 all fall within 1.2% of its score.

For a desktop builder, the TITAN BLACK is the obvious pick if raw compute is the priority. Its 5.645 TFLOPS FP32 throughput and 336.0 GB/s bandwidth place it in a different class from the MX330. The MX330's 1,224.2 GFLOPS FP32 and 56.06 GB/s bandwidth are appropriate for lightweight tasks in compact laptops, not for demanding workloads.

For a laptop user, the MX330 makes sense as a low-power option. Its 10 W TDP means it can exist in thin-and-light systems without active cooling requirements beyond what the chassis already provides. The TITAN BLACK's 250 W TDP and dual-slot cooler make it impossible to integrate into such a device.

The architectural generation gap shows in API support. The MX330 supports DirectX 12 (12_1) and Vulkan 1.4, while the TITAN BLACK is limited to DirectX 12 (11_1) and Vulkan 1.2.175. For modern games that leverage newer API features, the MX330 has a compatibility edge despite being far slower. For raw throughput, the TITAN BLACK is the clear winner.

Head-to-Head Benchmarks

The database records two shared benchmark tests between these GPUs. The GTX TITAN BLACK wins both, and the margins are enormous.

In Geekbench OpenCL, the TITAN BLACK scores 27218 against 7896 for the MX330. That is a 244.7% delta, meaning the TITAN BLACK delivers more than triple the OpenCL performance. This test benefits heavily from the TITAN BLACK's 2880 shading units and 336.0 GB/s memory bandwidth.

In Geekbench Vulkan, the TITAN BLACK scores 29561 against 9019 for the MX330. The delta is 227.8%. Interestingly, the TITAN BLACK's Vulkan score is higher than its OpenCL score, while the MX330's Vulkan score is also higher than its OpenCL score. Both GPUs gain from the Vulkan API compared to OpenCL, but the absolute gap remains roughly similar.

The overall benchmark averages reflect these results. The TITAN BLACK averages 9474 across all recorded tests, while the MX330 averages 8458. The TITAN BLACK's percentile versus all GPUs is 46, compared to 43 for the MX330. Both sit near the middle of the database, but the TITAN BLACK sits higher.

It is worth noting the TITAN BLACK has a broader benchmark profile in the database. It records scores for Geekbench Metal, OpenCL, and Vulkan, plus PassMark DirectX 9, 10, 11, 12, G2D, G3D, and GPU Compute tests. The MX330 only records Geekbench OpenCL and Vulkan scores. The TITAN BLACK's PassMark DirectX 11 score of 73 and DirectX 9 score of 133 show strong legacy API performance, while its PassMark G3D score of 9184 and GPU Compute score of 3726 round out the picture.

Where Each One Wins

The GTX TITAN BLACK wins in every recorded benchmark category. Its strengths are most pronounced in compute-heavy workloads: OpenCL and Vulkan performance are both more than three times that of the MX330. The TITAN BLACK also wins on bandwidth (336.0 GB/s versus 56.06 GB/s), pixel rate (58.80 GPixel/s versus 25.50 GPixel/s), and texture rate (235.2 GTexel/s versus 38.26 GTexel/s). If the task is rendering, video encoding, or any GPU-accelerated compute, the TITAN BLACK is the clear choice.

The MX330 wins in efficiency and portability. Its 10 W TDP versus 250 W means it generates a fraction of the heat and requires no external power. It is an IGP, meaning it can be soldered into a laptop motherboard. The TITAN BLACK requires a dual-slot cooler, a 600 W suggested PSU, and a 267 mm length, which confines it to full-size desktop cases. The MX330 also has a newer API profile with DirectX 12 (12_1) and Vulkan 1.4, which may matter for compatibility with newer software titles.

The MX330 also wins on transistor density, 24.3M per square millimeter versus 12.6M. This is a manufacturing efficiency metric rather than a performance one, but it explains how NVIDIA achieved the MX330's low power draw in a small package.

For a desktop workstation or gaming rig, the TITAN BLACK is the only sensible choice. Its 5.645 TFLOPS FP32 throughput is over 4.6 times the MX330's 1.224 TFLOPS. Its 48 ROPs versus 16 means better fill-rate-bound performance. Its 384-bit memory bus feeds data at six times the rate of the MX330's 64-bit bus.

For a thin-and-light laptop, the MX330 is the practical option. The TITAN BLACK cannot physically fit, and its power draw would overwhelm any portable chassis. The MX330's 2 GB VRAM is limited, but adequate for light gaming, media playback, and general desktop acceleration.

The database shows no benchmark category where the MX330 beats the TITAN BLACK. The wins column is 2-0 in favor of the TITAN BLACK. The MX330's advantages are architectural: newer process node, higher clocks, better API support, and dramatically lower power consumption. These are real benefits, but they serve different use cases than raw performance.
