If an old game was hard coded to use this intruction set, will it no longer work?
I hate it when games are coded like that - DoW II springs to mind, you HAVE to have a page file or it just craps out
Isn't this just an evolutionary process by AMD and a replacement will be on the cards? I know it's speculation and if it did have something on the cards, it would have been "leaked" by the AMD pr machine already. Let's just hope they've changed their crappy practices and will be launching an alternative.
I remember MMX coming out. All the high street retailers got rid of all the hardware without MMX before Christmas and then released all the new gear in the following new year. I remember watchdog going nuts about it on BBC1.
3DNow! was basically AMD's version of MMX. I haven't heard of anyone using it over SSE the last years, or at all during the past ten.
Everything seems to be about SSE and derived versions now: http://en.wikipedia.org/wiki/Streaming_SIMD_Extensions#Later_versions
3DNow Professional is the name used for the modern-day API, which has the feature set of SSE1 through 3: http://en.wikipedia.org/wiki/3DNow!
I guess since SSE and 3DNow were using the same functional units on the CPU anyway, it didn't appear to have any real relevance to AMD any longer.
I didn't know 3Dnow was still around. Haven't heard anything about it in years. Ah man, this brings me back
yeah old school.. it worked well back in quake 2
Just concentrate on SSE5, AMD.
AFAIK the last game engine which uses 3DNow is Id tech 4. Guys at Id software always did a good job of optimizing their games...
No one optimizes for hardware like id Software optimize for hardware!
I don't think there's any such game. It would mean the game would only work on AMD processors and I don't think there's any developer stupid enough to do such a thing.
That is nearly 100 instruction gone. I wonder how many transistors will it save.
SSE has 70, SSE2 has 144, SSE3 has 13. SSSE has 16, and SSE has 47. And with AVX we get another 100+
That is 390+ left.
Does that mean Bobcat wont have 3D Now and MMX? ( Great News )
Other sites are reporting that AMD is saying that any program that needs 3DNow! are still supported by the SSE extensions, so there will be no difference for the user.
