Re:does the new vlim4 architecture bring significant improvements? - 2010/12/18 16:28
Apart my critics in front of the last AMD products I have to admit the company did a good job considering they put a great power in so small gpus like the 5850 and 5870 are.
The 6950 and 6970 are instead a clear step backwards in terms of real architecture innovations and design.
Not to speak about the confusing 6850 and 6870 cards.
Recently many web sites did review the 6870 and targetted it as a best choise when compared to the 5850 and 5870 old models.
This consideration came out when the 6870 was compared to the 5870 by performing the unigine heaven benchmark.
Now having acquired that the tesselation processor inside the last models is a single thread based one some simple and approssimative calculations may be done in order to determine why the 6870 is slightly faster than a 5870...the performance secret is represented by the gpu frequency clock...therefore the amount of smd units did not alter the performance so much, probably at all.
The offensive part in this full story is that AMD is trying to let believe their customers that their tessellator has been restyled...it can be simply proven the contrary by pushing the 5850 and 5870 cards to 900 mhz and then the magic will happen.
Probably instead the 6870 card tessellator uses less resources but its own single thread task is to process data picked once per time...a recipe this one that is old like the human being.
In conclusion we are in front of two useless products like the 6850 and 6870 respective ones and as for the 6950 and 6970 we are in front of an old machine which body has been restored.
This time AMD did a very bad work...they started very well with the introduction of the 5xxx series and then they lost.
Is AMD sick? Maybe we can help and cure their disease...giving them some $$$ would help?
