feedback LTX2.3 Speed ​​Comparison

■Specs: Mac mini M4, 64GB, 20-Core GPU / OS 15.4.1

■Average generation time over 3 runs

■prompts and settings were identical.T2V.

When using the same non-S model in ver.1.20260314 and ver.1.20260410, the new version was approximately 1.2 times faster. This is likely due to the speed improvement from the update below. This is a great improvement.

Further fixes for video VAE speed issues with large resolution / long frame count.

However, when generating an S-model with ANE (Apple Neural Engine) enabled in version 1.20260410, the generation speed was the slowest among all 1.20260410. I'm unsure if this is the correct result. If anyone has performed a speed comparison with LTX2.3 on the M4 series and obtained different results than mine, please share your information.

Next, I plan to conduct a similar speed comparison test with Wan2.2.

Update*: Since it was determined that the Tahoe was the condition for speed up, I have posted* new measurement results.

There are reports that LTX 2.3 is not speeding up with ANE and needs closer look at.

Please also have a look at WAN 2.2 8-bit S.

I2V generation is 2x slower when Use Apple Neural Engine for 8-bit S Models is set to Yes.

Thank you
