GPU MODELS / ALTERNATIVES TO L40S
Alternatives to the L40S
The L40S is the workhorse of the inference-and-fine-tuning middle: Ada tensor cores with FP8, 48 GB of memory, and a price well below the H100 line. It has no NVLink, so multi-GPU scaling is PCIe-limited - but for single-card and small-fleet serving, it is the most common answer on the panel, and often the best $/token in the catalog.
People usually compare the L40S against A100 80GB, L40, H100 PCIe. Prices below are live on-demand published rates from the panel.
LOADING LIVE DATA...
| Alternative | Memory | Bandwidth | Cheapest live rate | Head to head |
|---|---|---|---|---|
| A100 80GB | 80 GB HBM2e | 2.0 TB/s | - | L40S vs A100 80GB |
| L40 | 48 GB GDDR6 ECC | 864 GB/s | - | L40S vs L40 |
| H100 PCIe | 80 GB HBM2e | 2.0 TB/s | - | L40S vs H100 PCIe |
WHEN EACH ALTERNATIVE WINS
A100 80GB
L40S has more FP16 compute on paper, but GDDR6 bandwidth is less than half the A100's HBM2e and 48 GB caps model size. For 70B-class work the A100 wins; for smaller models the L40S is usually cheaper per token.
L40
Same card with graphics-first tuning: the L40S trades some RT/raster throughput for roughly double the tensor compute. For AI work, always the L40S; for rendering, the L40.
H100 PCIe
H100 PCIe adds HBM bandwidth, FP8 maturity and 80 GB - at 2-4x the hourly rate. L40S owns the middle market.
L40S ALTERNATIVES - FAQ
What is the best alternative to the L40S?
It depends on the workload. A100 80GB: The 80 GB A100 in either form factor is the market's reference point for large-model work: enough HBM to fine-tune 70B-class models, enough bandwidth to keep tensor cores fed, and a huge installed base that keeps hourly rates competitive. L40: The L40 is the graphics-first sibling of the L40S: same 48 GB of GDDR6, full Ada RT cores, half the tensor throughput. H100 PCIe: The H100 PCIe puts Hopper's Transformer Engine into standard servers at half the SXM power budget. Live rates for each are in the table above.
Why look for L40S alternatives?
70B-class training or serving - 48 GB GDDR6 and no NVLink are hard limits.
How much does the L40S cost compared to its alternatives?
Each alternative's current cheapest published rate is listed in the table above; figures recompute hourly from provider-published prices.
