It's been 10 months since Intel launched its Nehalem architecture, and we showed you the Core i7 920, 940, and 965 Extreme Edition. Nothing much has changed in this high-end area since Core i7 processors are still brutally fast and equally expensive.
The cheapest option was launched at $ 280 as the Core i7 920, and that's exactly what it costs today. The Core i7 940 has been replaced by the 950, which offers a small performance upgrade and the same fee of ~ $ 570, while the flagship Core i7 965 Extreme Edition is replaced by the even more powerful 975 Extreme Edition at $ 1,000 .
Although the processor front has largely remained the same, there is now a large selection of X58 motherboards with more than fifty products from half a dozen manufacturers. If you know where to look, you can buy one for just $ 170, with the more luxurious models starting at $ 400.
Another big change is linked to the decline in prices for DDR3 memory. When we tested the Core i7 processors last November, a three-channel 6GB kit cost at least $ 250. Today, you don't have to spend more than $ 100. This means you can buy a Core i7 920 with motherboard and memory for less than $ 600 today. And although this may sound like a killer deal to some, not everyone needs the computing power of the Intel platform for enthusiasts or is willing to spend the money on it.
The Core i5 750 is the first version of a series of processors based on a mainstream version of the Core i7 platform. It is a quad core part based on the "Lynnfield" architecture, manufactured in a 45nm process and will use a new LGA1156 platform. This new chip costs only $ 199. It runs at a healthy 2.66 GHz and has a full 8 MB L3 cache. However, there will be no hyper-threading support.
When we first heard of the upcoming release of a mainstream version of the Core i7, we were thrilled with the idea, aside from Intel's decision to use multiple platforms. However, the new LGA1156 socket will support a number of new Intel processors, including the Core i3 and Core i5 series. There will also be a range of Core i7 processors designed for the socket above.
To reduce the cost of this processor and LGA1156 platform, Intel removed one of the memory controllers and replaced the high bandwidth QPI connection with the slower DMI chip-to-chip connection.
On the next few pages, we will go into more detail about Intel's revised desktop CPU range, the new P55 chipset (LGA1156) and our usual benchmarks that offer this new processor with the current Core 2 Quad offerings Core i7 920 and Core i7 920 compare the AMD Athlon II X4 965.
