1. If you listen closely... you can hear several AMD fanboys whining on the background...

2. Seems like a terrible idea.
An instruction for accelerating *one* specific encryption algorithm?
The thing about encryption algorithms is that they tend to change. The ones used 20 years ago aren't really good enough today. And 5 or 10 years from now? We'll just have a bunch of useless instructions, suitable for implementing obsolete algorithms.

3. So will it be a repeat of AMD's 64-bit instructions.. when Integrated Electronic goes something like.. *we shall not use the AMD 64 bit instructions* ;P

4. That is a shame that Intel is dropping SSE SIMD instructions for in place instructions to speed up special encryption/decryption algorithms. Like someone said previously, encryptions and decryptions now will be obsolete tomorrow. It is best to keep on including more SIMD instructions to increase processor efficiency. IMHO, AMD is on to something about SSE5 providing more efficiency to the end user. Present and new encryption/decryption can use future SIMD instructions to speed them up. Adding encryption/decryption instructions in ROM will be a waste of space which will rarely be used in the future.

Intel needs to re-think.

Intel has already implemented the CRC intsruction in SSE4 and specific string search/scan functions.

The ATA is a great idea in terms of optimizing speed. And when the encyption/decryption algos become obsolete in 10 years, well, the CPUs would have became obsolote a LOT before that.

Adding SSE will just confuse developpers even more. Let's face it, most applications out there are still not using any SSE at all!

The obsolete processors are used by robotic engineers and embeds. Including encryption and decryption algorithms is a waste. SSE5 and above can be used to decrease the time the processor takes to encrypt and decrypt data. SSE can be used for future un-invented encryption and decryption algorithms. Adding encryption and decryption SIMD just makes the processor slightly bigger and more costly.

SSE is used to decrease the amount of time a processor to calculate data for video, sound, graphics, or any mathematical problem. In simpler terms, it converts a very complex algebraic formula into a simpler formula like E=mc^2.

5. They are doing this to win benchmarks what else?
