Pentium D 805 Vs Athlon XP 2600+

[phaxmohdem]

Would a Pentium D 805 (2.66 GHz) be greater than or equal in performance to an AthlonXP 2600+ (2.13gHz) in single threaded apps? Would it a be a "mind blowing" upgrade for use in multithreaded apps such as dedicated 3d scene rendering?

It (PD 805) would be slower in single threaded apps...faster in multithreaded. This does not include any overclocking.

The 805 may actually be faster in single-threaded apps, too. It WILL be WAY faster in multi-threaded apps, but it won't shine unless you overclock it.

I don't think Overclocking would really be in the picture. It would honestly be shoved into a 2U server case and used specifically for rendering Lightwave 3D frames. Thought it might be cool if I could render 2 frames in the same time it currently takes to render 1. And since the 805 is so damn cheap it's looking very tempting.

I don't know Furen, a 2.66 GHz 533 FSB Netburst chip vs a 2.13 GHz AXP...seems to me that the 2600+ would have a distinct advantage in single thread.

I didn't know that you were using Lightwave...it's a multithreaded app. The 805 would be better...

Just for the record the Athlon XP runs on a 266MHz FSB with only 256K L2 Cache (not a Barton core) Which may hold it back a bit.

Doesnt matter. The Baron 2800+ runs at a lower frequency than the Thoroughbred 2600+.

Single-threaded app performance should be more or less the same (2600+ AXP amounts to a 2.66Ghz Northwood).

How soon you need it? Supposedly all the Netburst chips will see good price cuts later this year. We're talking about 900 series 65nm dual core with 800MHz FSB for just over $100. Those will be faster and run cooler than the 805.

Intel Launches Conroe in Two Months, Dual-Core Chips to Cost from $93

Intel is planning, if the slides published are to be believed, a price slash on the 4th of June, when it will lower the whole-sale cost of Intel Pentium D 960 to $224, whereas the models 930, 920 and 820 will cost $178. On the 23rd of July, Intel will decrease the pricing of Intel Pentium D 960, 950, 945, 940 and 820 to $316, $224, $163, $183, $133 and $113, respectively. Meanwhile, its Pentium D 805 will cost only $93, starting from that date.

Translation: July 23rd, Pentium D 940 will cost $133 in quantities, hopefully with street prices to match. The 940 is 3.2GHz 65nm dual core. Can you afford to wait just under 2 months?

Yup I can definately afford to wait. P-D 940 for that price would fit the bill nicely. Especially given the cramped living quarters of a 2U case. Thanks for the heads up.
