Speeds are estimates for a single request — one conversation at a time — calculated from memory bandwidth, model size and quantisation. Real throughput varies with the inference runtime and its version. Figures published by hardware vendors measure many simultaneous requests and are much higher.

What the numbers mean

What the memory subsystem means for AI

Memory

4 GB

Bandwidth

176 GB/s

Largest model

DeciLM 6B

Radeon R9 380 OEM carries only 4 GB of GDDR5. That limits it to the smaller end of the catalogue, and a model has to fit entirely inside before it generates anything at all. A runtime actually gets about 3.6 GB.

Memory bandwidth reaches 176 GB/s across a bus of 256 bits. Bandwidth is this card's real constraint. Every token requires reading the entire model out of memory, so a large model will feel slow here even when it fits.

Bandwidth is clock times bus width, and this card clocks its memory at 1.38 GHz. Both halves matter, and neither is visible in a gaming benchmark.

The practical ceiling is DeciLM 6B, 5.7B, compressed to Q3_K_M and generating around 27.5 tokens per second.

The chip and how it was built

Radeon R9 380 OEM is built on the graphics processor Antigua, using the architecture GCN 3.0 from AMD, as part of the generation Pirate Islands(R9 300).

The chip is manufactured by TSMC, on a process of 28 nm, with a die measuring 366 mm², holding 5 billion transistors. A smaller process generally means more performance for the same power, though for language models it matters far less than the memory subsystem.

It was released in May 2015, roughly 11.360796859516 years ago. Inference software support tends to follow hardware by a year or two, so a card of this age generally has mature, well-optimised code paths available to it.

Compute throughput, and why it matters less than it looks

FP16

3.3 TFLOPS

FP64

205.6 GFLOPS

On paper Radeon R9 380 OEM reaches 3.3 TFLOPS at half precision, and 3.3 TFLOPS at single precision. These are peak figures no real workload sustains, and generating text reaches only a small fraction of them — decoding is limited by memory rather than arithmetic, which is why a card can look enormously powerful here and still produce tokens at an ordinary rate.

Double-precision throughput reaches 205.6 GFLOPS. It has no bearing on running a language model — no inference runtime uses it — but it separates datacentre parts from consumer ones, since the latter deliberately restrict it.

Clocks run from a base of 918 MHz to a boost of 918 MHz. Worth far less here than on a gaming benchmark: raising the clock speeds up the arithmetic, and the arithmetic is not what generation is waiting on.

Cache and processing units

Radeon R9 380 OEM has an L1 cache of 16 KB, backed by an L2 cache of 0.5 MB. Cache absorbs a share of the memory traffic that would otherwise hit the main bus, which is the one place on this page where a number other than bandwidth quietly affects generation speed — a large L2 lets more of the working set stay close to the cores.

There are 1,792 shading units, 112 texture mapping units, and 32 render output units. These drive graphics workloads and contribute to prompt processing, but they sit idle for much of the time a model spends generating a reply.

Power, size and installation

Power draw

190 W

Radeon R9 380 OEM is rated at 190 W, and the suggested system power supply is 450 W. Running a language model keeps a card busy in bursts rather than continuously — it draws hard while generating and idles between requests — so sustained draw over a working day is usually well below the rated figure.

The board occupies dual-slot, measuring 221 mm long, and needs 2x 6-pin. Worth checking against the case and power supply already in the machine, since the largest cards need considerably more of both than a typical desktop provides.

It connects over PCIe 3.0 x16. The interface governs how quickly a model is loaded from disk into the card, not how fast it runs once there, so a narrower link costs a few seconds at startup and nothing thereafter.

Step by step

How to work out the tokens per second of a Radeon R9 380 OEM

You do not have to calculate anything by hand — the gputps.com calculator on this page has already worked it out for every model this card can hold. Reading off the answer takes six steps.

  1. 01

    Search for the model you want

    The table lists 105 models this card runs. Search narrows the list by name or by size.

  2. 02

    Set the context length you will actually use

    Longer conversations cost memory on top of the weights. Against 4 GB so the setting is worth getting right.

  3. 03

    Choose how far you will compress

    Each model is shown at the best compression this card can hold. A minimum quality hides the ones that only fit by being squeezed further than you would accept.

  4. 04

    Look at the range, not just the number

    Speeds come with error bars for a reason. The best case here is 68.2 tok/s on Gemma 4 E2B. The same card and model vary by thirty to fifty per cent between inference runtimes.

  5. 05

    Check the memory column before committing

    The fit column separates models that just fit from those with room to spare — worth checking before settling on one, against an available 4 GB.

  6. 06

    Check the same model from the other side

    Following a model through to its own page lists all the hardware that can run it, so you can see how it compares against Radeon R9 380 OEM.

Answers

Radeon R9 380 OEM — common questions

01

Radeon R9 380 OEM— is it good for running local AI models?

Its memory limits it to smaller models though its bandwidth means generation will feel slow on larger models. In total it runs 105 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.

02

Radeon R9 380 OEM— can it run a model that does not fit in its memory?

Offloading past the card's 4 GB sit in system memory and run at a fraction of the speed, so a mostly-offloaded model is rarely worth using. Every figure here assumes it is fully resident on the card.

03

Would two Radeon R9 380 OEM cards be twice as fast?

No. A second card doubles the memory to 8 GB of combined memory, at roughly the same generation speed as one.

04

Radeon R9 380 OEM— which AI models can it run?

105 of the 721 open-weight language models we track fit on this card and can be run locally. The table on this page lists every one, with the memory it needs, the quantisation it runs at and an estimated generation speed.

05

Radeon R9 380 OEM— what is the largest AI model it can run?

The largest model in our catalogue that fits is DeciLM 6B at 5.7B parameters, compressed to Q3_K_M. It generates roughly 27.5 tokens per second and needs about 3.5 GB of the card's memory.

06

Radeon R9 380 OEM— how many tokens per second does it produce?

It depends on the model. The fastest model we track here is Gemma 4 E2B at about 68.2 tokens per second, while larger models run proportionally slower because each token requires reading the whole model out of memory once. Speeds are estimates for a single conversation at a time.

07

Radeon R9 380 OEM— how much memory does it have?

This card has 4 GB of GDDR5. Around a tenth is reserved by the inference runtime and the driver, leaving roughly 3.6 GB available for a model and its conversation.

08

Radeon R9 380 OEM— what is its memory bandwidth?

Memory bandwidth reaches 176 GB/s across a bus of 256 bits. This is the single best predictor of how fast it generates text, because producing each token means reading the entire model out of memory once.

09

Radeon R9 380 OEM— what type of memory does it use?

It uses GDDR5 clocked at 1.38 GHz. HBM types are found on datacentre accelerators and carry far more bandwidth than the GDDR used on desktop cards, which is why they generate tokens considerably faster at the same capacity.

10

Radeon R9 380 OEM— who makes it?

This is a product of AMD, with the chip manufactured by TSMC, on a process of 28 nm.

11

Radeon R9 380 OEM— when was it released?

It was released in May 2015.

12

Radeon R9 380 OEM— how much power does it use?

Rated board power is 190 W, and the suggested system power supply is 450 W. Generating text draws hard in bursts and idles between requests, so average consumption over a working session is normally well below the rated figure.

13

Radeon R9 380 OEM— how much cache does it have?

The L1 cache is 16 KB, and the L2 cache is 0.5 MB. Cache absorbs part of the memory traffic that would otherwise reach the main bus, so a larger L2 gives a modest lift to generation speed beyond what bandwidth alone predicts.

14

Radeon R9 380 OEM— what are its TFLOPS?

It is rated at 3.3 TFLOPS at half precision and 3.3 TFLOPS at single precision. These are peak arithmetic ceilings rather than achievable rates, and text generation reaches only a small fraction of them because it is limited by memory bandwidth instead.

15

Radeon R9 380 OEM— does it support CUDA?

No. CUDA is NVIDIA-only, and this is a card from AMD. It runs language models through ROCm, Vulkan or Metal depending on the software, which are less mature than the CUDA path — our estimates apply a penalty for that.

16

Radeon R9 380 OEM— what bus interface does it use?

It uses PCIe 3.0 x16. This governs how fast a model is loaded onto the card rather than how fast it runs once loaded, so it costs a few seconds at startup and nothing during generation.

The other direction

Looking at it from the other side?

This page starts from the hardware. If you already know which model you want and need to know what it takes to run it, start from the model instead.
