Q: Which GPU has the higher pixel and texture fill rates?

A: The GTX 880M leads decisively: its pixel rate is 31.78 GPixel/s versus 13.38 GPixel/s for the GTX 465, and its texture rate is 127.1 GTexel/s versus 26.75 GTexel/s. The GTX 880M also has more texture mapping units (128 vs 44) and more shading units (1536 vs 352).

Architecture Differences

The GTX 465 is built on NVIDIA's Fermi architecture, specifically the GF100 chip, fabricated on a 40 nm process at TSMC. The GTX 880M uses the Kepler architecture with the GK104 chip, also from TSMC but on a newer 28 nm node. This process shrink allows the GTX 880M to pack 3,540 million transistors into a 294 mm² die, while the GTX 465 has 3,100 million transistors in a much larger 529 mm² die. The resulting transistor density is dramatically different: 12.0M per mm² for the GTX 880M versus 5.9M per mm² for the GTX 465.

The shading unit count shows a massive difference: the GTX 880M has 1536 shading units, compared to 352 on the GTX 465. This is a 4.36x increase. Texture mapping units follow a similar pattern, with 128 on the GTX 880M versus 44 on the GTX 465. Both cards have 32 ROPs, so the render output stage is identical in count. The memory subsystem also differs: the GTX 880M comes with 8 GB of GDDR5, while the GTX 465 has 1 GB. Both use a 256-bit bus, but the GTX 880M runs its memory at 1250 MHz (5 Gbps effective) versus 802 MHz (3.2 Gbps effective) for the GTX 465.

The APIs supported differ in Vulkan: the GTX 880M supports Vulkan 1.2.175, while the GTX 465 has no Vulkan support listed. Both cards support DirectX 12 (11_0) and OpenGL 4.6. The GTX 465 uses a PCIe 2.0 x16 interface, while the GTX 880M uses an MXM-B (3.0) interface, reflecting its mobile-oriented design. The GTX 465 is a dual-slot desktop card with 2x 6-pin power connectors and a 200 W TDP, whereas the GTX 880M is an MXM module with no power connectors and a lower 122 W TDP. Display outputs also differ: the GTX 465 has 2x DVI and 1x mini-HDMI 1.3a, while the GTX 880M is described as "Portable Device Dependent."

Head-to-Head Benchmarks

The only recorded head-to-head benchmark is Geekbench OpenCL, and it is a decisive victory for the GTX 465. The GTX 465 scores 9294 points, while the GTX 880M scores 5622 points, a delta of 65.3%. This means the GTX 465 outperforms the GTX 880M by nearly two-thirds in this compute-oriented workload.

This result is striking given the GTX 880M's newer architecture, higher clock speeds (954 MHz base, 993 MHz boost versus none listed for the GTX 465), and far greater shading unit count. The GTX 880M also has a much higher theoretical FP32 throughput of 3.050 TFLOPS versus 855.4 GFLOPS for the GTX 465. Yet the actual OpenCL score does not follow that theoretical advantage. The database shows the GTX 465 leading by 65.3%, indicating that the benchmark workload favors other aspects of the GTX 465, possibly its older driver stack or memory latency characteristics, which are not captured in the specification fields.

Looking at the broader context, the GTX 465's score of 9294 places it just below the NVIDIA GeForce GTX 850M (9302, 0.1% higher) and just above the NVIDIA GeForce GTX 960 (9273, 0.2% higher). The GTX 880M, with its score of 5622, is far lower in the performance hierarchy, sitting near the NVIDIA Quadro P5000 (8039, 0% delta) and the NVIDIA GeForce GTX 650 Ti (8053, 0.2% higher). The GTX 880M's average score of 8040 is actually pulled down by its OpenCL score of 5622; it also has a separate Geekbench Metal score of 10458, which is not part of the average but shows a different workload.

In summary, the GTX 465 wins the only head-to-head test by a wide margin. The data does not record any test where the GTX 880M wins; the wins tally is 1 for the GTX 465 and 0 for the GTX 880M.

The Verdict

The data clearly favors the NVIDIA GeForce GTX 465 in the only available head-to-head benchmark: the Geekbench OpenCL score shows a 65.3% advantage over the GTX 880M. The GTX 465 also has a higher average benchmark score overall (9294 vs 8040) and a higher percentile rank (46th vs 42nd). For users who prioritize OpenCL compute performance, the GTX 465 is the decisive pick based on measured results.

However, the GTX 880M offers several specification-level advantages that may matter in other scenarios. It has 8 GB of memory versus 1 GB, a 55.8% higher memory bandwidth (160.0 vs 102.7 GB/s), and far higher pixel and texture fill rates (31.78 vs 13.38 GPixel/s, and 127.1 vs 26.75 GTexel/s). Its theoretical FP32 throughput is 3.050 TFLOPS versus 855.4 GFLOPS, and it has many more shading units (1536 vs 352). The GTX 880M also runs at a lower TDP of 122 W versus 200 W, making it a more efficient design for mobile platforms.

The GTX 465 also carries a launch MSRP of 279 USD, but the database does not record a launch MSRP for the GTX 880M. The GTX 465 is a desktop dual-slot card with a PCIe 2.0 x16 interface, while the GTX 880M is an MXM module designed for portable devices, so the choice may also come down to platform.

Who should pick which? If the workload is compute-oriented and measured by Geekbench OpenCL, the GTX 465 wins outright. If the workload benefits from the GTX 880M's higher memory capacity, higher bandwidth, and higher fill rates, and the user is on a portable platform, the GTX 880M is the better option. The data does not record any test where the GTX 880M wins, so the only recorded benchmark tilts entirely toward the GTX 465. Users seeking a card within the GTX 465's performance class should also consider the GTX 850M or GTX 960, which are within 0.2% of its score. For the GTX 880M, the Quadro P5000 is essentially identical (0% delta) in average score.
