TestFlight beta
Same models, same prompts, measured the same way, so the only thing left to compare is the chip. RapidInference runs four real AI workloads on your iPhone, with nothing sent to a server, and gives it one score you can put next to anyone’s.
Home, after a full run. Tap Run full benchmark to watch it again.
Gemma 4 E2B answering the first question of the benchmark on an iPhone 18 Pro, replayed at the speed the phone measured. Eleven questions in, the chip is hot and the same model manages about 40. The score counts both.
Janet’s ducks lay 16 eggs per day. She eats three for breakfast every morning and bakes muffins for her friends every day with four. She sells the remainder at the farmers’ market daily for $2 per fresh duck egg. How much in dollars does she make every day at the farmers’ market?
Pace from the reference run on 22 September 2026. The wording of the reply is ours; the speed is the phone’s.
The Neural Engine goes first. After a few minutes of GPU work the whole chip throttles, and measured last, the second Neural Engine’s advantage simply disappears. Then the language model, the fine-tune and the images, all on the GPU through MLX.
EDSR ×2 super-resolution on 25 overlapping tiles of a harbor photo, swept across one, two and four lanes on the Neural Engine, then the GPU and the CPU.
The first 20 problems of GSM8K, answered greedily, up to 512 tokens each. Speed is timed on the first five and the last five, so the score sees how much a warm chip slows down.
16 of 20 answered correctly on the reference phone, the same 16 as on a Mac.
150 steps of QLoRA on 500 rows of WikiSQL, teaching Qwen3 to turn questions into SQL. It asks three everyday questions before and after, so you can see what it learned.
QWhat is the capital of Japan?
ASELECT Capital FROM countries WHERE Country = 'Japan'
Text to image at 512 × 512 with a ternary FLUX.2 [klein]. The text encoder, transformer and decoder load one at a time, so the whole thing fits in about 3 GB.
Measured on iPhone 18 Pro, 22 September 2026. Slowed down 10× so you can watch it happen.
The A20 Pro has two. To find out, RapidInference cuts a 1024 × 1024 harbor photo into 25 overlapping tiles and upscales each one ×2 with EDSR, sending them down one, two or four lanes at once.
A single engine takes one request at a time, so extra lanes just queue up. With two, the second lane runs alongside the first: 145 tiles a second instead of 85.

Like Geekbench, points are anchored to a real phone. Twice as fast scores twice as much, and there’s no ceiling. Only speed earns points: a wrong answer can take them away, never add them. Memory and heat sit beside the score as badges, not inside it.
points = 5,000 × your speed ÷ the reference · bars fill at 6,250
Lowered by wrong GSM8K answers. Badges: peak memory, and how much speed holds.
Lowered by a worse validation loss. Badge: peak memory.
Badge: peak memory.
Lowered if the upscale gains less sharpness over plain resizing.
Each test is the weighted geometric mean of its speed metrics; the overall score is the geometric mean of the four. Quality can lower a score to half, never raise it. Reports keep raw numbers, so old runs are rescored when the reference moves.
The models download in the background, even with the phone locked. A Live Activity follows them on the Lock Screen and in the Dynamic Island, in 5% steps, and tells you when they’re ready.
0 B
of your prompts, pictures and reports leave the phone. Scores go to Game Center only if you’re signed in.
64 GB
of models, fetched once, resumed if the Wi-Fi drops, and kept out of your iCloud backup.
A phone that’s already warm waits up to five minutes before the suite starts, so no run begins throttled. In a hurry? There’s a Skip button.
Reports save the raw numbers and the images, not just the score.
Five Game Center boards. Every score carries its chip, so phones get ranked, not just players.
Share a card with your score, your chip and where your phone ranks.
Simulator runs are never submitted. A run you leave halfway isn’t scored. Fixed prompts, fixed seeds, fixed order, every time.
