Intel Penryn Performance Preview: The Fastest gets Faster

a performance pouco ganha (ok +- +15% :D) mas sao mt mt economicos de energia e mt freskinhos.... isto cum um x38 e ddr3 temos Oc e performance 5+ :D
 
Preview da HKEPC do Penryn onde comparam um Wolfdale Dual Core com um Core2Duo, ambos a 2.33Ghz

Reparem no resultado de 115.63% de aumento de desempenho numa alpha do divx com suporte para SSE4. No mínimo impressionante.
 
porque razao e que ha Xeons QUAD Core a 50W e da gama "caseira" o minimo dos quad core e quase o dobro?

ainda e uma diferenca grande
 
"Tudo" sobre o Penryn:
“Intel Advanced Smart Cache technology receives additional enhancements, besides the increased L2 cache. Penryn-based quad and dual-core processors will have up to 12MB and 6MB L2 cache, respectively. Intel reduces cache latency in addition to the larger sizes. Penryn features a 24-way associative cache, an upgrade from Conroe’s 16-way associative cache.

New to the Advanced Digital Media Boost technology is the inclusion of a new Intel SSE4 instruction set. SSE4 introduces 47 new instructions to improve performance of video accelerators, graphics building blocks and streaming load. Intel claims a 2x performance gain in video acceleration tasks. There are 14 new instructions for video accelerator performance enhancement. Intel improves compiler auto-vectorization performance with 32 new instructions.“

The new SSE instructions may play a major role in increasing the performance of media encoding/editing programs. It's unknown whether or not the new instructions could have other potential uses. The large L2 cache(s) could certainly offer some performance gains, especially for anyone doing a lot of heavy multi-tasking. For users who are running only one program, it will still likely offer some performance gains, but just how much will vary from program to program.
Despite the enhanced size of the L2 caches, they are also rumored to have lower latencies. This means that programs that occupy a large portion of the cache could receive an even larger performance boost. From an engineering standpoint, it's quite hard to increase the size and reduce the latency. Generally if cache sizes go up, latency stays the same or takes a small performance hit. If Intel can accomplish both at once while keeping the price reasonable, we'll be impressed.
While these two feature are the easiest to talk about, there are a few others that could end up being very important. Chief amongst these are the enhanced division capabilities (4 bytes/cycle vs. 2.), improved Intel VT (with lower latencies) and improved power management which should help keep those electric bills down.

Although Intel set the launch dates for quad-core Xeon based Penryn processors, the company remains silent on the launch date of the desktop and mobile counterparts.

Acho que se calhar já não é este ano.. talvez no ínicio do próximo.

Cumprimentos
 
Agora estou na dúvida...

Boas .

Agora estou na dúvida,se valerá a pena esperar e comprar na altura um Penryn QUAD core a bom preço,para a minha EVGA 680I SLI (caso os venha a suportar) ,com as minhas actuais memorias DDR2 1066 SLI,ou investir agora mesmo num QUAD Q6600 GO ,o que é que acham da ideia,o que é que vosses faziam ?

Muito Obrigado.

Depende da tua emergência e da tua bolsa..Se puderes aguentar até ao lançamento dos Penryn acho que vale a pena..pois em termos de Quad Cores o leque de escolha vai aumentar..e a nível de preços há para varias bolsas..e claro..ganhos de performance face aos actuais modelos..

Contudo..se não aguentas a espera aventuras-te agora e pouco antes do Penryn sair vendes o G0..perdes algum €..mas já se sabe que é o mal da informática..
 
E esses processadores, os quad core, vao ser suportados pelas motherboards actuais como a asus p5k.

E quanto vai custar um desses quad cores, um mais ou menos equivalente ao q6600?
 
Yorkfield is a Ray-Trace monster

CHIPHZILLA SHOWED A DEMONSTRATION of Ray-Tracer on its latest processors, and we have to say that the demo was quite a surprise to us.

Who knows, maybe in a year CPUs might be good for graphics again.

The reason for this is because of the advances made by the RT group inside Intel. Daniel Pohl, author of Quake III and IV Ray-Trace demonstrations held a presentation that showed that Ray-Trace came from 4FPS in 640x480 resolution on a 50 Xeon CPUs machine to over 90 FPS (frames per second) in 768x768 on a single machine with Yorkfield processor running at sub-3GHz clockspeed.

We all know that oldXeon was a Netbust, but this difference is just insane.

The demo machine was based on a Gigabyte's X38 motherboard, two AMD Radeon HD 2900XT cards in CrossFire mode, Corsair memory, and Intel 45nm quad-core processor, known to most people as Yorkfield. However, graphics part was not used at all, so you could have GeForce 8400 or Radeon HD 2400, this render would work as fast.

This does not stop here, since the upcoming "Skulltrail" system will feature two Yorkfield processors with regular memory, making V8 rev2 a very powerful and more affordable system. Judging from what we saw in the morning, 8-core dual-Yorkfield system should be able to run the fascinating demonstrations in 1280x720. This would be a first for HD resolution with no major issues (or actually 1280x1280), but we will have to wait until Q4 to see that one.

Bear in mind that this demonstration did not include some of the special effects used in world of RT, because support for SSE4 is still not implemented. Scaling is at nearly 100%, so with every extra core you will get around 99% scaling boost, or a near-perfect code.

The lads in RT development plan to enable Intel's Ray Tracer available for gaming developers, so that Ray-Trace can become a reality. Timeframe for delivery is early 2009, and if you are great in logical games, we will leave you to calculate with what Intel product is planned to come in the same timeframe.
