1st promptCold start — includes initialization
>Write a Python function to sort a list
Here's a Python function that sorts a list using quicksort:
def quicksort(arr):
if len(arr) <= 1:
return arr
pivot = arr[len(arr) // 2]
left = [x for x in arr if x < pivot]
middle = [x for x in arr if x == pivot]
right = [x for x in arr if x > pivot]
return quicksort(left) + middle + quicksort(right)
# Example usage
numbers = [3, 6, 8, 10, 1, 2, 1]
print(quicksort(numbers)) # [1, 1, 2, 3, 6, 8, 10]
The algorithm picks a pivot, partitions the list into smaller, equal, and larger elements, then recursively sorts each partition and concatenates the results.
2nd promptWarm — model ready, no init overhead
>Now add type hints and a docstring
def quicksort(arr: list[int]) -> list[int]:
"""Sort a list using the quicksort algorithm.
Args:
arr: List of integers to sort.
Returns:
A new sorted list.
"""
if len(arr) <= 1:
return arr
pivot = arr[len(arr) // 2]
left = [x for x in arr if x < pivot]
middle = [x for x in arr if x == pivot]
right = [x for x in arr if x > pivot]
return quicksort(left) + middle + quicksort(right)
Added type hints for the input and return type, plus a Google-style docstring.

What limits this setup
It fits through host-memory offload, and offload is the main reason performance drops.
CPU or host-memory offload is active
About 20% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Older PCIe generation
PCIe 3.0 is workable, but it compounds the penalty when you offload heavily or try to scale across multiple cards.
Best improvement path
Remove offload with more accelerator memory
Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
Increase host RAM if you keep offloading
This setup may need roughly 0.5 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Frequently asked questions
Can GTX 1080 Ti 11GB run StarCoder 7B?
Yes, GTX 1080 Ti 11GB can run StarCoder 7B at Q3_K_S quantization (Very compromised (needs ~0.5 GB host RAM)). The recommended Q4_K_M requires 13.9 GB which exceeds available memory, but at Q3_K_S it needs only 13.1 GB. Expected decode speed: 38.8 tok/s.
How much VRAM does StarCoder 7B need?
StarCoder 7B (7B parameters) requires approximately 13.9 GB at Q4_K_M quantization. On GTX 1080 Ti 11GB, it fits at Q3_K_S using 13.1 GB.
What is the best quantization for StarCoder 7B?
The recommended quantization is Q4_K_M, but on GTX 1080 Ti 11GB the best fitting quantization is Q3_K_S, which uses 13.1 GB.
What speed will StarCoder 7B run at on GTX 1080 Ti 11GB?
On GTX 1080 Ti 11GB, StarCoder 7B achieves approximately 38.8 tokens per second decode speed with a time-to-first-token of 4993ms using Q3_K_S quantization.
Can GTX 1080 Ti 11GB run StarCoder 7B for coding?
For coding workloads, StarCoder 7B on GTX 1080 Ti 11GB receives a F grade with 29.2 tok/s and 8K context.
What context window can StarCoder 7B use on GTX 1080 Ti 11GB?
On GTX 1080 Ti 11GB, StarCoder 7B can safely use up to 8K tokens of context at Q3_K_S quantization. The model's official context limit is 8K, but available memory constrains the safe maximum.
What should I upgrade first if StarCoder 7B feels slow on GTX 1080 Ti 11GB?
Remove offload with more accelerator memory. Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
