Capacity and bandwidth
Memory
8 GB
Bandwidth
154 GB/s
Largest model
Baichuan 1-13B
At 8 GB of GDDR5 the Zhongshan Subor Z+ GPU is limited to the smaller end of the catalogue. About 7.2 GB is actually available to a runtime, and a model has to fit entirely inside it before generating anything at all.
At 154 GB/s across a 256-bit bus, 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.
The figure is the memory clock — 1.2 GHz here — multiplied by the bus width. It is why core counts predict generation speed so poorly.
Put together, the largest model that fits is Baichuan 1-13B at 13.3B, running Q3_K_M and producing around 10.3 tokens per second.
The chip and how it was built
The Zhongshan Subor Z+ GPU is built on the Fenghuang graphics processor, using AMD's GCN 5.0 architecture, as part of the Console GPU(Zhongshan Subor) generation.
The chip is manufactured by TSMC, on a 14 nm process, with a die measuring 397 mm². 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 August 2018, roughly 7 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
8 TFLOPS
FP64
249.6 GFLOPS
On paper the Zhongshan Subor Z+ GPU reaches 8 TFLOPS at half precision and 4 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 is 249.6 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 1.3 GHz at base to 1.3 GHz boosted. 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
There are 1,536 shading units, 96 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
100 W
The Zhongshan Subor Z+ GPU is rated at 100 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.

Step by step
How to work out the tokens per second of a Zhongshan Subor Z+ GPU
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.
-
01
Start with the model, not the specification
Every one of the 337 models this Zhongshan Subor Z+ GPU runs is in the table above. Search narrows it by name or by size.
-
02
Decide how long your conversations run
Set the context to your real working length. Short questions cost almost nothing; a long document can consume a large share of the card's 8 GB.
-
03
Set a minimum quality if you need one
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.
-
04
Take the range as the answer
Each speed is an estimate for a single conversation, with a range beneath it — 50.7 tok/s on Gemma 3 QAT 1B at the top end here. The same card and model vary by thirty to fifty per cent between inference runtimes.
-
05
Check the memory column before committing
Compare what each model needs with the 8 GB this card provides. Tight means it works today; comfortable means it still works when the conversation grows.
-
06
Check the same model from the other side
Each model page repeats this calculation for the whole catalogue. Worth a look before deciding: it shows what else runs the same model, and how the Zhongshan Subor Z+ GPU compares.
Answers
Zhongshan Subor Z+ GPU — common questions
Who makes the Zhongshan Subor Z+ GPU?
The Zhongshan Subor Z+ GPU is a AMD product, with the chip manufactured by TSMC, on a 14 nm process.
When was the Zhongshan Subor Z+ GPU released?
The Zhongshan Subor Z+ GPU was released in August 2018.
How much power does a Zhongshan Subor Z+ GPU use?
The Zhongshan Subor Z+ GPU has a rated board power of 100 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.
What are the TFLOPS of a Zhongshan Subor Z+ GPU?
The Zhongshan Subor Z+ GPU is rated at 8 TFLOPS at half precision and 4 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.
Does the Zhongshan Subor Z+ GPU support CUDA?
No. CUDA is NVIDIA-only, and the Zhongshan Subor Z+ GPU is a AMD card. 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.
Is the Zhongshan Subor Z+ GPU 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 337 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.
Can a Zhongshan Subor Z+ GPU run a model that does not fit in its memory?
Offloading past the card's 8 GB is possible and usually a false economy: the system-memory portion is slow enough to dominate the result.
Would two Zhongshan Subor Z+ GPU cards be twice as fast?
Capacity adds, throughput does not. Two of them give you 16 GB to work with rather than twice the tokens per second — every figure here is for a single Zhongshan Subor Z+ GPU.
What AI models can a Zhongshan Subor Z+ GPU run?
337 of the 679 open-weight language models we track fit on a Zhongshan Subor Z+ GPU and can be run locally on it. The table on this page lists every one, with the memory it needs, the quantisation it runs at and an estimated generation speed.
What is the largest AI model a Zhongshan Subor Z+ GPU can run?
The largest model in our catalogue that fits on a Zhongshan Subor Z+ GPU is Baichuan 1-13B at 13.3B parameters, compressed to Q3_K_M. It generates roughly 10.3 tokens per second and needs about 7.2 GB of the card's memory.
How many tokens per second does a Zhongshan Subor Z+ GPU produce?
It depends on the model. On a Zhongshan Subor Z+ GPU the fastest model we track is Gemma 3 QAT 1B at about 50.7 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.
Can a Zhongshan Subor Z+ GPU run a 7B model?
Yes. For example a Zhongshan Subor Z+ GPU runs MetaMath 7B (LLaMa finetune) at Q4_K_M, using about 6.5 GB of memory and generating around 16.7 tokens per second.
Can a Zhongshan Subor Z+ GPU run a 13B model?
Yes. For example a Zhongshan Subor Z+ GPU runs Gemma 4 12B at Q3_K_M, using about 6.5 GB of memory and generating around 11.5 tokens per second.
How much memory does a Zhongshan Subor Z+ GPU have?
A Zhongshan Subor Z+ GPU has 8 GB of GDDR5 memory. Around a tenth of that is reserved by the inference runtime and the driver, leaving roughly 7.2 GB available for a model and its conversation.
What is the memory bandwidth of a Zhongshan Subor Z+ GPU?
The Zhongshan Subor Z+ GPU has 154 GB/s of memory bandwidth, across a 256-bit memory bus. 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.
What type of memory does a Zhongshan Subor Z+ GPU use?
It uses GDDR5 clocked at 1.2 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.
