NVIDIA GeForce GT 545 vs NVIDIA RTX 5000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The most striking finding in the data is how closely these two GPUs match in aggregate benchmark scores, despite representing completely different eras of NVIDIA hardware. The NVIDIA RTX 5000 Mobile Ada Generation averages 3596 points across its benchmark suite, while the NVIDIA GeForce GT 545 averages 3594 points. That is a delta of just 0.1% in favor of the RTX 5000 Mobile Ada Generation. In practical terms, the two cards are statistically indistinguishable in the single benchmark result recorded for each.

The RTX 5000 Mobile Ada Generation achieves its score in the 3DMark Steel Nomad DX12 test, a modern, DirectX 12 Ultimate workload that stresses ray tracing and mesh shading. The GT 545, by contrast, records its 3594 points in Geekbench OpenCL, a compute-oriented benchmark that measures raw throughput rather than gaming features. This matters because the two benchmarks are not directly comparable in workload character. The data shows the RTX 5000 Mobile Ada Generation delivering 3596 in a demanding modern DirectX 12 test, while the GT 545 posts 3594 in a legacy compute test. The near-identical scores therefore do not imply equal gaming performance — they simply reflect that both cards land at the 21st percentile among all GPUs in the database.

Looking at the nearest rivals for each card reinforces the picture of a dense, tightly-packed cluster. The RTX 5000 Mobile Ada Generation's nearest competitors are the GT 545 itself (delta 0.1%), the GT 735M (delta -0.6%), the GTX 1050 (delta -0.9%), and the AMD Radeon HD 6770 (delta -1.5%). The GT 545's nearest rivals are essentially the same group: the RTX 5000 Mobile Ada Generation (delta -0.1%), GT 735M (delta -0.6%), GTX 1050 (delta -1.0%), and Radeon HD 6770 (delta -1.5%). Both cards sit in a performance band where a 1.5% swing separates them from the Radeon HD 6770 at the bottom and a 0.9% swing separates them from the GTX 1050 above.

The biggest single gap in either direction is the RTX 5000 Mobile Ada Generation's 1.5% lead over the Radeon HD 6770, and the GT 545's identical 1.5% margin over the same card. Neither GPU has a decisive win in either direction over its nearest rivals. The RTX 5000 Mobile Ada Generation edges out the GT 545 by 0.1%, but the GT 545 edges out the GT 735M by the same 0.6% that the RTX 5000 Mobile Ada Generation also holds. This is a statistical dead heat, not a hierarchy.

What is genuinely remarkable is the architectural gulf hidden behind these scores. The RTX 5000 Mobile Ada Generation carries 9728 shading units, 304 texture mapping units, and 112 ROPs, with 76 dedicated ray tracing cores and 304 tensor cores. The GT 545 has just 144 shading units, 24 TMUs, and 16 ROPs, with no ray tracing or tensor hardware whatsoever. Yet the benchmark scores land within 0.1% of each other. The explanation lies in the benchmark choice: the GT 545's OpenCL score rewards its modest compute throughput in a way that does not reflect its gaming limitations, while the RTX 5000 Mobile Ada Generation's Steel Nomad score is a far more demanding test. In a head-to-head gaming scenario, the data suggests the RTX 5000 Mobile Ada Generation would win decisively — but the recorded benchmarks do not show that because they are different tests.

The Verdict

The data supports a clear split decision based on use case, not raw benchmark scores. For anyone running modern DirectX 12 Ultimate workloads, the RTX 5000 Mobile Ada Generation is the only viable choice. It supports DirectX 12 Ultimate (12_2), Vulkan 1.4, has 76 ray tracing cores, 304 tensor cores, and 16 GB of GDDR6 memory. The GT 545 supports only DirectX 12 (11_0) with no Vulkan support, no ray tracing, and no tensor cores. Its 1536 MB of DDR3 memory on a 192-bit bus delivers 38.40 GB/s — a tiny fraction of the RTX 5000 Mobile Ada Generation's 576.0 GB/s.

For legacy compute tasks or basic 2D workloads, the GT 545's 3594 OpenCL score shows it can still hold its own in that narrow context. But the architecture data makes the choice obvious: the RTX 5000 Mobile Ada Generation delivers 41.15 TFLOPS of FP32 compute versus the GT 545's 414.7 GFLOPS — a 99-fold difference. The RTX 5000 Mobile Ada Generation also offers 236.9 GPixel/s pixel rate versus 4.320 GPixel/s, and 643.0 GTexel/s texture rate versus 17.28 GTexel/s. The benchmark scores do not reflect these enormous differences because they are different tests; any modern workload that uses the RTX 5000 Mobile Ada Generation's features will see a massive advantage.

The GT 545 is a single-slot, 70 W card with a 250 W suggested PSU, designed for 2011-era desktops with PCIe 2.0 x16. The RTX 5000 Mobile Ada Generation is an integrated (IGP) mobile part with a 120 W TDP, no power connectors, and PCIe 4.0 x16. They are not competing for the same socket, chassis, or user. The verdict is straightforward: the RTX 5000 Mobile Ada Generation for any modern or future workload, the GT 545 only for retro compatibility or non-demanding legacy compute.

Specification Differences

The two cards diverge on nearly every specification. The RTX 5000 Mobile Ada Generation uses an AD103 chip on a 5 nm TSMC process with 45,900 million transistors on a 379 mm² die. The GT 545 uses a GF116 chip on a 40 nm TSMC process with 1,170 million transistors on a 238 mm² die. Transistor density tells the story: 121.1 million transistors per mm² for the RTX 5000 Mobile Ada Generation versus 4.9 million for the GT 545.

Memory differs completely: 16 GB GDDR6 on a 256-bit bus with 576.0 GB/s bandwidth versus 1536 MB DDR3 on a 192-bit bus with 38.40 GB/s bandwidth. The memory clock is 2250 MHz (18 Gbps effective) on the RTX 5000 Mobile Ada Generation versus 800 MHz (1600 Mbps effective) on the GT 545.

Compute resources: 9728 shading units, 304 TMUs, 112 ROPs, 76 RT cores, 304 tensor cores versus 144 shading units, 24 TMUs, 16 ROPs, and no RT or tensor cores. Pixel rate is 236.9 GPixel/s versus 4.320 GPixel/s. Texture rate is 643.0 GTexel/s versus 17.28 GTexel/s. FP32 is 41.15 TFLOPS versus 414.7 GFLOPS. The RTX 5000 Mobile Ada Generation has 1:1 FP16 at 41.15 TFLOPS; the GT 545 lists no FP16 capability.

Clocks: the RTX 5000 Mobile Ada Generation runs at 1425 MHz base and 2115 MHz boost. The GT 545 lists no base or boost clock.

The GT 545 has a launch MSRP of 149 USD; the RTX 5000 Mobile Ada Generation has no launch MSRP listed.

Architecture Differences

The RTX 5000 Mobile Ada Generation is built on the Ada Lovelace architecture, the successor to Ampere-MW and predecessor to Blackwell-MW. It is a 5 nm TSMC part with 45,900 million transistors and a 379 mm² die. The GT 545 uses the Fermi 2.0 architecture, from the GeForce 500 generation, built on a 40 nm TSMC process with 1,170 million transistors and a 238 mm² die. Fermi was succeeded by GeForce 600; Ada Lovelace succeeded Ampere-MW and was succeeded by Blackwell-MW.

The architectural differences are fundamental. Ada Lovelace implements a modern GPU design with dedicated ray tracing cores (76) and tensor cores (304), enabling hardware-accelerated ray tracing, DLSS-style AI features, and DirectX 12 Ultimate support (12_2). Fermi 2.0 has no such specialized hardware. The RTX 5000 Mobile Ada Generation supports Vulkan 1.4 and OpenGL 4.6; the GT 545 has no Vulkan support and only DirectX 12 (11_0) — meaning it cannot run DirectX 12 Ultimate features despite the version number.

Cache hierarchies differ implicitly through the huge transistor count disparity — 45,900 million versus 1,170 million — though the FACT PACK does not list cache sizes. The memory architecture is also generational: GDDR6 with a 256-bit bus versus DDR3 with a 192-bit bus. The RTX 5000 Mobile Ada Generation's 576.0 GB/s bandwidth is 15 times the GT 545's 38.40 GB/s.

The RTX 5000 Mobile Ada Generation has a 1:1 FP16 ratio, meaning its tensor cores can process FP16 at the same rate as FP32 — 41.15 TFLOPS for both. The GT 545 lists no FP16 capability at all. The RTX 5000 Mobile Ada Generation's 76 RT cores and 304 tensor cores are entirely absent from the GT 545, which relies on 144 shading units for all computation. The Ada Lovelace generation also brings PCIe 4.0 support versus the GT 545's PCIe 2.0, doubling available host bandwidth.

The production status reflects the architectural gulf: the RTX 5000 Mobile Ada Generation is Active, the GT 545 is End-of-life. The RTX 5000 Mobile Ada Generation's 5 nm process enables 121.1 million transistors per mm² versus 4.9 million for the 40 nm GT 545. That 25-fold density advantage, combined with 12 years of architectural evolution, explains why a 120 W mobile IGP can outclass a 70 W desktop card in every specification except the narrow benchmark scores recorded.
