Both Multiply Accumulate have corresponding modes, so depending on the IP settings, both may produce the same result.
Each has the following differences.

[Arria 10 Native Floating Point DSP IP]

• Specialized for implementation of 1 DSP block (resources are not ALM assuming 1 DSP block), only single precision floating point numbers are supported
• Fine-tuning of the Hardware Floating Point DSP block
• A calculation engine that partially parallelizes large-scale Multiply Accumulate calculations can be used as a material for users to design HDL.

[Floating Point IP (ALTERA_FP_FUNCTIONS)]

• Supports other families such as the V series, supports double precision floating point numbers and other precisions
• May result in no use of DSP blocks (specify non-use)
