Intel Core i7-3820

When you're building your own computer, the first thing to decide is: How much of an enthusiast do you want to be? If you have the desire and the money, you can go for an all-out bleeding-edge system; if not, there are usually more reasonable options. Well, the Intel Core i7-3820 CPU is certainly reasonable by the standards of the company's Sandy Bridge–Extreme line: Priced at $294 list, it's noticeably less expensive than either the top-tier Core i7-3960X Extreme Edition ($999 list) or the nipping-at-its-heels Core i7-3930K ($583 list). With the Core i7-3820 you'll still get a fine chip for your money, but you'll have to sacrifice the eye-popping performance and features of the pricier chips to get it. If you're okay with that, you'll be okay with this CPU. The Core i7-3820's differences are apparent just from its specs. In several ways it is much the same as its bigger brothers: It's based on the same 32nm production process, it has the same 130-watt TDP, and it will require you to also have an X79 Express motherboard (with the LGA2011 socket), a discrete video card (there's no integrated graphics system on the chip), and a separate CPU cooler (Intel doesn't bundle one with any CPU in this line). But there the similarities end.

Intel Second Generation Core i7 3820 Review

Introduced back in November of 2011, Intel's Sandy Bridge Extreme processors came as a long-awaited update to the company's high-end enthusiast line. Socket 1366 and the X58 chipset have served well, but at this point in time, even a mid-range 2600K Sandy Bridge-based system can really push past the performance of a quad-core Socket 1366 processor. Now a little long in the tooth, it is time for a refresh. At its onset, Intel's Sandy Bridge Extreme platform was catered to the upper crust of the market, with the 6-core Core i7 3960X priced at $999. The Core i7 3930K was released at around $550, but Sandy Bridge-E was still lacking a "value" option for mainstream consumers. That is, until the release of the quad-core Core i7 3820, which is priced at just over $300. Socket 1155 Sandy Bridge processors, like the Core i7 2600K, have already proven to be potent performers, so what makes the step up to the SNB-E i7 3820 appealing for the X58 or Socket 1155 owner? Off the bat, it sees an increase in PCIe lanes from 16 to 40, support for PCIe 3.0, quad-channel memory with support for up to 64 GB of total system memory, increased L3 cache and computing performance, a bump in frequency to 3.6 GHz, Turbo Boost 2.0, a partially-locked chip for Sandy Bridge-style overclocking, and new instruction sets.

Intel Core i7-3820 Processor Review

Late last year when we reviewed the new Sandy Bridge-E processors, we mentioned a more affordable version called the Core i7-3820 was coming. Although information about the chip had been revealed, the processor has yet to hit shelves and is now expected to arrive later in February. Fortunately, sample units are being passed around ahead of general availability, so we don't have to wait to see how it stacks up. The i7-3820 is particularly intriguing because of its sub-$300 retail price -- far less than other chips in the series. For instance, the Core i7-3960X has an MSRP of $999 and sells for more like $1,049, while the i7-3930K has an MSRP of $583 and is fetching $599 at e-tail. Both are six-core CPUs operating over 3GHz with massive 15MB and 12MB L3 caches. At roughly half the price of the 3930K, we expected Intel to butcher the i7-3820, and while that's partially true, the 3820 remains an impressive specimen with four cores operating at 3.6GHz, a 10MB L3 cache and HyperThreading support. Compared to the similarly priced i7-2600K, the 3820 offers additional L3 cache, support for PCI Express 3.0, quad-channel memory and a platform that will take as much as 32GB of system memory.

Intel Core i7 3820 review

This is a bit more within the reach of us mere mortals - a Sandy Bridge E CPU that doesn't cost the same amount as some full PCs.Intel, with even less of a fanfare than it made for the muted launch of the Sandy Bridge E platform, has now unleashed the quad-core iteration of its top-end chips, the Intel Core i7 3820, priced at £260 in the UK and $286 in the US. But, to be honest, we're not entirely sure why this CPU even exists.Before this, the cheapest Sandy Bridge E processor was the Intel Core i7 3930K, costing £450-500 in the UK and $650-700 in the US. The crazy expensive £800-900/$1,100-1,200 Intel Core i7 3960X takes its place at the top of the Intel CPU tech tree. Both those CPUs are full-blooded hex-core chips with Hyper-Threading tech enabling twelve threads of processing power.Except that they're not really hex-core chips at all. The Intel Core i7 3930K and i7 3960X are actually octo-core server chips with a couple of cores disabled to fit into the desktop segment.This, coupled with the huge price tag, has been our major bugbear with the latest of Intel's top-end chips. We now have eight-core CPUs potentially running in our home rigs, but unfortunately we're not allowed access to the disabled silicon sitting inside our incredibly expensive chips.

Intel Core i7-3820 Quad-Core Sandy Bridge-E CPU Review

A few weeks back, we took a look at the Core i7-3960X, Intel's first desktop processor to feature the company's Sandy Bridge-E microarchitecture. If you're unfamiliar with the chip, Sandy Bridge-E is the ‘tock' in Intel's tick-tock release schedule cadence that bridges the gap between first-gen Sandy Bridge-based processors like the Core i7-2700K and next year's Ivy Bridge microarchitecture. Sandy Bridge-E shares many of the same features of the original Sandy Bridge microarchitecture, but as the \"E” denotes, SBE is a more extreme derivative, targeted at enthusiasts. In our launch coverage of the Intel Core i7-3960X, we take a deep-dive look at Sandy Bridge-E and detail many of its features, like its 40 integrated PCIe 3.0-class lanes, quad-channel memory controller configuration, new socket and chipset, 32nm manufacturing process, and many others. We'd highly recommend checking out that article, because it lays all of the groundwork necessary to fully appreciate the processor we'll be showing you today, the Core i7-3820. We briefly discussed the Core i7-3820 in our Core i7-3960X coverage, but didn't have a chip on hand for testing.

CPU Reviews

The Intel Core i7 3820 is the poor relative of the very pricey Core i7 3960X. Both these processors are part of the Sandy Bridge-E family and include the same features (Hyper-threading, Turbo) but differ in their running clocks and, most importantly, number of cores. The i7 3960X has six cores whereas the i7 3820 has four. The i7 3820 therefore still has Hyper-threading, which allows you to double the number of cores seen by the operating system artificially. It’s clocked at 3.6 GHz and this can go up to 3.9 GHz when Turbo mode kicks in. In practice, the Core i7 3820 is an excellent processor at ease with all types of task as well as in games. The overall difference in performance with the Core i7 3960X is a little under 15%. The i7 3820 is also 15% up on the Core i7 2700K (LGA 1155 platform). Available at a lot less than the 3960X, this 'little’ 3820 therefore represents a much more affordable entry to Intel's high-end platform (LGA 2011). For a more thorough analysis of the series of Core i7 3000s with four and six cores, we refer you to our full test of the Intel Core i7 3960X.
