Intel Corp. has revealed official performance advantage expectations for its next-generation microprocessors code-named Ivy Bridge. Thanks to new micro-architectural improvements, the world's largest chipmaker expects Core i 3000-series processors to deliver up to 25% better performance than existing Core i 2000-series "Sandy Bridge" chips in office applications and up to 199% improvements in graphics intensive apps.
ntel recently started to spread its official Ivy Bridge performance expectations among its partners, manufacturers of personal computers and resellers. The documents by Intel, which have leaked to the Internet, demonstrate that Intel rather high expectations for its next-generation Core i 3000-series microprocessors when it comes to general purpose performance and especially graphics performance. According to the documents, Intel Core i7-3770 (4 cores with HyperThreading, 3.40GHz, 8MB cache) will deliver the following advantages compared its predecessor Core i7-2600 (4 cores with HyperThreading, 3.40GHz, 8MB cache):
+7% higher overall SYSmark 2012 score;
+14% higher overall HDXPRT 2011 score;
+15% higher Cinebench 11.5 score;
+13% better ProShow Gold 4.5 result;
+25% faster performance in Excel 2010;
+56% faster performance in ArcSoft Media Expresso;
+192% higher overall 3DMark Vantage score;
+17% faster performance in 3DMark Vantage CPU benchmark;
+199% faster performance in 3DMark Vantage GPU benchmark;





Ivy Bridge will generally inherit Sandy Bridge micro-architecture and will sport a rather significant number of improvements. Firstly, it will have certain improvements that will boost its performance in general applications by around 20% compared to Core i "Sandy Bridge" chips (e.g., enhanced AVX acceleration). Secondly, the forthcoming chip will have a new graphics core with DirectX 11 and OpenCL 1.1 support, 30% higher performance compared to the predecessor as well as new video processor and display controllers. Thirdly, Ivy Bridge will feature PCI Express 3.0 x16 interconnection as well as PCIe 2.0 x4 controller. In fourth, the processor will support a number of power management innovations. The CPU is made using 22nm process technology.

Intel will release its code-named Ivy Bridge central processing units for desktops in March or April, 2012.

Intel did not comment on the news-story since the documents describing Ivy Bridge performance are not made available for general public.

Le soluzioni Core i7 integreranno tutte architettura quad core con tecnologie HyperThreading e Turbo Boost, abbinate ad una dotazione di cache L3 da 8 Mbytes unificata tra i core.; per le numerose versioni Core i5 troveremo invece architettura quad core senza tecnologia HyperThreading e cache L3 da 6 Mbytes, fatta solo eccezione per il modello Core i5-3470T che sarà dotato di due core con HyperThreading e cache L3 da 3 Mbytes.

A differenziare le soluzioni Ivy Bridge troveremo, al pari di quanto visto anche con le proposte Sandy Bridge, anche il sottosistema video. Per Ivy Bridge la GPU integrata potrà essere della serie HD Graphics 4000 oppure HD Graphics 2500: tra le due parti avremo un numero di execution unit variabile, presumibilmente superiore di 1/3 nella proposta HD 4000. La frequenza di clock di base sarà pari a 650 MHz, con la possibilità di spingersi sino a valori ben più elevati a seconda della specifica versione di processore raggiungendo quale massimo i 1.150 MHz, utilizzando ovviamente la tecnologia Turbo Boost.

Molto interessanti i valori di TDP dichiarati per questi processori: troviamo infatti livelli di 77 Watt per le CPU Core i7 e Core i5 di tipo standard, mentre per le versioni caratterizzate dal suffisso S il TDP scende sino a 65 Watt. A seguire le versioni T, con TDP contenuto in 45 Watt fatta eccezione per il modello Core i5-3470T che ha TDP pari a 35 Watt grazie proprio all'integrazione di due soli core con tecnologia HyperThreading contro i 4 delle altre versioni di processore Ivy Bridge.

vy Bridge micro-architecture, planned for the second quarter 2012, will bring a number of enhancements to CPU and graphics portions of the chip. The CPU cores will feature up to 15%, sometimes even higher performance due to micro-architecture improvements and 100 MHz - 300 MHz higher Turbo Boost frequencies. HD 4000 and HD 2500 graphics will add support for DirectX 11, and it will be considerably faster than current HD 3000 and HD 2000 on-chip graphics. What's more important, better performing Ivy Bridge CPUs will come with 20% lower Thermal Design Power. It's great that upcoming CPUs will run cooler and faster, but at what price? Based on pricing information, that we've seen, desktop Ivy Bridge SKUs will have prices, in most cases identical to Sandy Bridge predecessors.

The fastest and the most expensive processor from Core i7 series will be Intel i7-3770K CPU with unlocked clock multiplier. This 3.5 GHz quad-core chip will come with 8 MB L3 cache, Hyper-Threading, and up to 3.9 GHz Turbo Boost. The CPU will replace Core i7-2700K, and it will be priced the same, at $332.

Three remaining SKUs from Core i7 family, i7-3770, i7-3770S and i7-3770T, will cost $294 in 1K quantities. It's good to see that Intel continues to offer energy-efficient "S" and "T" models at the same price level as mainstream microprocessors.

Similar to current Sandy Bridge products, Ivy Bridge Core i5s will feature 4 CPU cores with 6 MB of last level cache. The only exception to this is a dual-core i5-3470T with 3 MB L3 cache. The fastest i5 chip will be i5-3570K, a successor to Core i5-2500K. This CPU will come with $225 price sticker. Other i5-35xx series products, namely Core i5-3550, i5-3550S and i5-3570T, will cost $205, or $20 cheaper than the i5-3570K. i5-34xx processors will be the most affordable from i5 family. There will be three of them available in Q2 2012 at $184: Core i5-3450, i5-3450S and i5-3470T.

Table below contains a summary of features of soon to be released Ivy Bridge processors. Dual-core Core i5-3470T will be available in May. Remaining 10 i5 and i7 models will launch in April. Prices of future IB processors are presented in the "Price"column. The last column in the table shows Sandy Bridge model, that will be replaced, or closely matches, upcoming IB CPU:
