Well the new Intel corei5 processors in the new role today in to be the next generation of the processor that has a base manufacturing from the Intel corei7 processors. They still have the same onboard memory controller that makes the latency of the memory to the CPU a breeze and creating a more universal chip in the process. With the P55 chip already having a brawl for buyers and also entry level buyers to look forward for the much better choice and also value even some of the parts required are a bit to look at first.
In the processor family of the new corei7 LGA1156 variants and the corei5 processors have the same architecture ore in some cases derived from the success of the Coei7 processors with the introduction of the QPI system in the CPU and integrating most of the controllers like the memory controller in the DDR memory, and including the introduction of the integration of the Northbridge controller, the P55 chipset will be integrated inside the corei5 and the corei7 LGA1156 variants, well we might see a obvious prize hike in the additional features in the CPU but make a better advantage in latencies.
For today’s release Intel has a pair of Core i7 processors, the Core i7-870 and the i7-860, both of which are quad-core processors with HyperThreading enabled to support 8 threads. The Core i5-750 is a quad-core part without HyperThreading but with the same 8MB L3 cache as the Core i7 offerings. Most of the part, the new Corei5 750, a middle mainstream processor with a main core spec is a standard core clock of about 2.66GHz with a capable feature that can unlock the core multiplier to increase the core frequency when the CPU experiences high load times, The base frequencies of these processors are in 133 MHz steps starting with the Core i5-750 @ 2.66 GHz and going up to 2.93 GHz on the Core i7-870. What is really more important though is the Turbo Frequencies listed here as you will likely very rarely see your CPU actually running at that base clock speed.
The i5-750 will definitely be the lowest cost processor with these performance levels available anywhere. By jumping up another $85 or so you can get a slightly higher base clock and Turbo Mode speeds as well as the added performance of HyperThreading. Moving up to the i7-870 will cost you $270 more but only get you a single stepping higher performance (133 MHz in base and Turbo Mode speeds) which definitely make the i7-860 the best overall value at first glance.
Clearly the big winner here is the Intel Core i5-750 in terms of performance for you dollar. What you might be interested to know is how much “worse” of a deal the Core i7-870 turned out to be - the performance/$ here in our sample benchmarks are about half that of the i5-750. I do think, however, had we had a Core i7-860 to test for this review, that IT would have been the CPU of choice for me in terms of nearly all our metrics including performance per dollar. I will definitely be getting one of these in soon for testing and see what we come up with.
While we have already discussed and gone over just about every aspect of the new Lynnfield processor in the previous pages, a nice, clean summary is in order. First, the Core i7-870 is indeed an incredibly powerful processor and in many of our tests and benchmarks was able to rival the scores of the Core i7-975 Nehalem CPU priced around $999 online. Considering the i7-870is about half that price, users that can afford to shell out the $555 or so for the unit should definitely not feel taken by the purchase.
The Core i5-750 is a more interesting discussion since, because it lacks HyperThreading support, it falls into a new class of CPU - “Nehalem architecture without HT.” It does indeed perform very well in our suite of benchmarks though in some cases if doesn’t come out much faster than the aging Q9650 based on the Yorkfield Core 2 architecture and even the AMD Phenom II X4 965 CPU. The price is right though, and as you can tell from our performance/$ rating above, that puts it in a very enticing position for anyone looking to build a system on a budget.
