A good book but...(update, formatting fixed)
Format: Kindle
A good book but the code in the Kindle edition is very badly formatted. The downloaded source code seems correct.
Update formatting issue seems to have been fixed.

Good for basic x86 64 but avx coverage is horrible.
Format: Paperback
After having read Irvine 7th I had a good knowledge of x32 but soon enough I realized it’s all obsolete so now it’s on to Hyde 64. The hello world program involves interfacing to c++ and assembly/linking with batch commands. Really? I’m using visual studio ide have you heard of build and run? Hyde doesn’t even mention the debugger and without this tool assembly language is impossible. But I was already familiar with this after reading Irvine so I was ok. The following chapters 2 to 9 about 600 pages worth are great so for what I paid the book is 4 stars. Great explanation, lots of complete programs. Now it’s time for parallel processing via Simd and avx and this is chapter 11, over 100 pages of instructions with no examples. It could be useful for reference but actually, no. Amidst all the formats, memory operand and register sizes the actual explanations of the instructions are vague. Well that defeats the purpose of thumbing this chapter as a reference doesn’t it? But where Hyde fails Kusswurm modern x86 begins. If you’ve made it this far sell Hyde, Irvine, and buy Kusswurm. Then you’ll have Jedi powers like me.

It benefits the high-level language programmers - Listing formatting good now
Format: Paperback, Format: Paperback
Even if not writing assembly code directly, it benefits the high-level language programmer to understand the CPU architecture and instruction set. You can help the compiler do a better job by writing your code with the hardware in mind. When it comes to debugging, it can be helpful to look at things at the assembly level.
And if you are programming with SIMD intrinsics, you are still programming in assembly language and understanding the architecture is necessary.
This book gets you up to speed with all the above and more.
Also, the listing formatting problem that others have mentioned seems to have been fixed. I deleted the months old download from my device, downloaded again, and the listing were now good. Tested on an iPad, a Kindle Paperwhite, and a MacBook Pro.
