NVIDIA GeForce 830M vs NVIDIA RTX 5000 Mobile Ada Generation Comparison

The NVIDIA GeForce 830M and the NVIDIA RTX 5000 Mobile Ada Generation are separated by nearly a decade of GPU architecture, and the benchmark data reflects a complete inversion of their respective positions in the performance hierarchy. While the 830M holds a modest lead in the available synthetic benchmark scores, the RTX 5000 Mobile exhibits a staggering advantage in raw compute capabilities, memory bandwidth, and modern feature support, making it the unequivocal choice for demanding professional workloads.

Head-to-Head Benchmarks

The available benchmark data presents a peculiar scenario where the older GeForce 830M actually outperforms the RTX 5000 Mobile in the specific tests recorded. The 830M achieves an average benchmark score of 3957, which places it in the 24th percentile of all GPUs. Its nearest rival, the AMD Radeon R5 M420, scores 3956, representing a 0% deltaPct, while the NVIDIA GeForce GT 745M trails at 3953 with a 0.1% deltaPct. The 830M also edges out the NVIDIA Quadro K2000 (3964, -0.2%) and the AMD Radeon HD 6850 X2 (3977, -0.5%).

In direct contrast, the RTX 5000 Mobile Ada Generation records an average benchmark score of 3596, placing it in the 21st percentile. Its nearest rivals include the NVIDIA GeForce GT 545 at 3594 (0.1% deltaPct), the NVIDIA GeForce GT 735M at 3616 (-0.6%), the NVIDIA GeForce GTX 1050 at 3629 (-0.9%), and the AMD Radeon HD 6770 at 3649 (-1.5%). This means that in the specific tests captured, the 830M holds a 10% advantage over the RTX 5000 Mobile in average benchmark score (3957 vs 3596).

However, this narrow comparison is misleading. The 830M's wins come from Geekbench OpenCL (4324) and Geekbench Vulkan (3590) tests, which measure compute and graphics workloads in a legacy context. The RTX 5000 Mobile's single recorded benchmark, 3DMark Steel Nomad DX12, scores 3596. This test is a modern DirectX 12 Ultimate workload that stresses ray tracing, mesh shaders, and other features that the 830M's Maxwell architecture cannot even execute. The data shows that the 830M wins the legacy compute tests, but the RTX 5000 Mobile is designed for a completely different class of application.

Architecture Differences

The architectural gulf between these two GPUs is profound. The 830M is built on the GM108 chip using the Maxwell architecture on a 28 nm process node at TSMC. It packs 1,020 million transistors into a 77 mm² die, yielding a transistor density of 13.2M / mm². In contrast, the RTX 5000 Mobile uses the AD103 chip with the Ada Lovelace architecture on a 5 nm process, also at TSMC, cramming 45,900 million transistors into a 379 mm² die for a density of 121.1M / mm². This represents a 9.2x increase in transistor density.

The core configurations are equally divergent. The 830M features 256 shading units, 16 TMUs, and 8 ROPs, with no ray tracing or tensor cores. The RTX 5000 Mobile, however, boasts 9,728 shading units, 304 TMUs, and 112 ROPs, alongside 76 dedicated ray tracing cores and 304 tensor cores. Clock speeds also differ substantially: the 830M runs at a base of 1082 MHz and a boost of 1150 MHz, while the RTX 5000 Mobile operates at 1425 MHz base and 2115 MHz boost.

Memory architecture is a stark differentiator. The 830M uses 2 GB of DDR3 on a 64-bit bus, yielding a bandwidth of just 14.40 GB/s. The RTX 5000 Mobile uses 16 GB of GDDR6 on a 256-bit bus, delivering 576.0 GB/s — a 40x increase in bandwidth. The effective memory speed jumps from 1800 Mbps to 18 Gbps. The RTX 5000 Mobile also supports PCIe 4.0 x16, while the 830M is limited to PCIe 3.0 x8.

Feature support highlights the generation gap. The 830M supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.4. The RTX 5000 Mobile supports DirectX 12 Ultimate (12_2), which includes hardware ray tracing, mesh shaders, and variable rate shading, along with the same OpenGL 4.6 and Vulkan 1.4. The RTX 5000 Mobile also has FP16 performance at 41.15 TFLOPS (1:1 ratio), while the 830M has no listed FP16 capability. Pixel rate jumps from 9.200 GPixel/s to 236.9 GPixel/s, and texture rate from 18.40 GTexel/s to 643.0 GTexel/s.

Where Each One Wins

The GeForce 830M wins in legacy compute benchmarks. Its Geekbench OpenCL score of 4324 and Geekbench Vulkan score of 3590 are its strongest showings, and its average benchmark score of 3957 exceeds that of the RTX 5000 Mobile. For users running older applications, OpenCL compute tasks, or Vulkan workloads that do not leverage modern hardware features, the 830M will deliver acceptable performance. Its 33 W TDP and IGP slot width also indicate it is designed for low-power, portable devices where battery life and thermal constraints are paramount. The 830M's nearest rivals — the Radeon R5 M420, GT 745M, Quadro K2000, and HD 6850 X2 — all cluster within 0.5% of its score, confirming it is a competent entry-level mobile GPU for its era.

The RTX 5000 Mobile wins in every modern compute and graphics metric that matters. Its FP32 performance of 41.15 TFLOPS is dramatically higher than the 830M's 588.8 GFLOPS, representing a 70x increase. Its texture rate of 643.0 GTexel/s is 35x higher than the 830M's 18.40 GTexel/s, and its pixel rate of 236.9 GPixel/s is 25.7x higher. The 76 ray tracing cores and 304 tensor cores enable hardware-accelerated ray tracing and AI-based features like DLSS, which are entirely absent on the 830M. The 16 GB GDDR6 memory with 576.0 GB/s bandwidth allows for large datasets, high-resolution textures, and complex scenes that would immediately exhaust the 830M's 2 GB DDR3 buffer. The RTX 5000 Mobile's DirectX 12 Ultimate support ensures compatibility with the latest games and professional applications, while the 830M is limited to DirectX 12 (11_0) feature levels.

The Verdict

The data is unambiguous. For anyone running modern workloads — 3D rendering, AI inference, video editing, or contemporary gaming — the RTX 5000 Mobile Ada Generation is the only viable choice. Its 41.15 TFLOPS FP32, 304 tensor cores, 76 ray tracing cores, and 576.0 GB/s memory bandwidth place it in an entirely different performance class. The 830M's 588.8 GFLOPS and 14.40 GB/s bandwidth are simply insufficient for such tasks. The RTX 5000 Mobile's 120 W TDP, while higher than the 830M's 33 W, is appropriate for a professional mobile workstation GPU.

However, the benchmark scores tell a nuanced story. The 830M's higher average benchmark score (3957 vs 3596) and higher percentile ranking (24th vs 21st) suggest that in lightweight, legacy workloads, it can actually outperform the RTX 5000 Mobile. This is because the RTX 5000 Mobile's drivers and architecture are optimized for modern, feature-rich workloads, and it may not be fully utilized by older, simpler compute tasks. For users with legacy software that only uses OpenCL or Vulkan 1.4 features, the 830M could provide adequate performance at a fraction of the power draw.

The 830M is end-of-life, released on 2014-03-11, with a successor in the GeForce 900M series. The RTX 5000 Mobile is active, released on 2023-03-20, succeeding the Ampere-MW generation. The production status alone indicates that the RTX 5000 Mobile is the future-proof option, while the 830M is a relic of a bygone era. The choice is clear: the RTX 5000 Mobile for any serious modern workload, and the 830M only for extremely constrained, legacy use cases where power efficiency and minimal thermal output are the absolute priorities.
