đánh giá i7 4770

Hãng Intel is in the process of releasing their new Haswell architecture next week at Computex. Luckily, we were able lớn find an Hãng Intel Core i7-4770 retail boxed hàng hóa for sale on Amazon.com this week. Since this was a retail purchased sản phẩm and not a sampled product under NDA / press embargo, this does not qualify as a leak. Just a first benchmark of the chip prior lớn the official release. Like the Ivy Bridge processors prior, Haswell is utilizing Intel’s 22nm tri-gate process technology. This go-round Intel has implemented much of the power circuitry previously found on motherboards now on-die. As one can see from the various “leaks” of motherboard pictures, Haswell socket LGA1150 motherboards have sầu significantly fewer power related components surrounding the processor socket. The Hãng Intel Vi xử lý Core i7-4770 is a 4 core 8 thread (thanks to lớn Hyper-Threading) processor.

Test Configuration

At ServeThetrang chủ we vì chưng honor NDAs & truyền thông media embargos so we are not going into great detail regarding which motherboard we are using. We will be doing several LGA1150 motherboard nhận xét in the next few weeks all from various vendors. We are also using our older previous Windows chạy thử suite for this Đánh Giá.

Other major details in the kiểm tra configuration:

Operating System: Windows 7 Enterprise

This should be sufficient for a basic build. More on LGA1150 motherboards this week.

Hãng sản xuất Intel Chip Core i7-4770 Performance Tests

I will start off this section by saying that the standard chạy thử suite was built khổng lồ test 1-8 thread single CPU systems. Examples are Sandy Bridge và Ivy Bridge Hãng Intel Xeon CPUs. Over time, we have been slowly altering the phối. Clearly, one would expect a different workload between dual Intel Xeon E5-2690 CPUs và something found in a low-kết thúc, low-power VPS like an Intel Pentium G21trăng tròn. Moving lớn the 16-64 core realm where the AMD Opterons and Intel Xeon E5 CPUs dominate, we utilize our Linux chạy thử suite which will be the standard going forward. In the coming days we will update those results with a more robust mix of processors to compare to lớn.

Cinebench R11.5

We have sầu been using Cinebench benchmarks for years. Cinebench has been added to the test suite because it does represent a valuable benchmark of multi-threaded performance. We have sầu had quite a few readers tương tác me about this type of performance for rendering performance. Cinebench R11.5 is something that anyone can run on their Windows machines khổng lồ get a relative idea of performance. After seeing Cinebench scale from one to 64 cores, it has become a favorite.

As we can see with the Cinebench results, the new Haswell architecture performs very well. Easily outpacing the Ivy Bridge generation parts.

7-Zip Compression Benchmark

7-Zip is an immensely popular compression application with an easy lớn use benchmark. It is also part of our Linux benchmark suite.

7-Zip benchmark results have sầu the Intel bộ vi xử lý Core i7-4770 at just about the same cấp độ as the Intel Vi xử lý Core i7-3770K. This is really showing off the IPC benefits of Haswell.

TrueCrypt Encryption Benchmarks

With Intel’s focus on its AES-NI features TrueCrypt can look a bit skewed. Unlượt thích some dubious drivers over the years that were optimized for benchmarks over real world application, Intel’s AES-NI feature does encompass the addition of specialized hardware. This specialized hardware has many practical uses. For example, users of Solaris 11 can utilize the AES-NI features khổng lồ see much higher throughput on encrypted volumes. AMD has started offering AES acceleration on many of its so it is a good chạy thử for most CPUs now. At the same time, modern processors are so fast that AES encryption is more or less “free” at any practical wire speeds.

Here we see some very interesting results. The Hãng sản xuất Intel Chip Core i7-4770 is almost as fast as dual AMD Opteron 4736HE processors & significantly faster than the Ivy Bridge generation. Here is a quiông chồng example of what a typical benchmark run looks like on the Hãng sản xuất Intel bộ vi xử lý Core i7-4770:

Strong performance all around.

Handbrake 0.9.5 x264 Encoding Benchmarks

We are still using Handbrake v0.9.5. This is just khổng lồ keep a consistent look at CPUs that have sầu been tested with v0.9.5. We will begin to lớn collect data on v0.9.6 và start using that once we have sầu critical mass. Either way, Handbrake is an extremely popular x264 encoding and transcoding application. It is very common practice these days to encode video for Mobile devices. Quichồng transcoding is an important CPU application.

Given the filters we are using, this is exactly what we would expect. The Hãng sản xuất Intel bộ vi xử lý Core i7-4770 is hitting the limits of the particular benchmark thiết đặt. Again, this is a benchmark started in the LGA1156 days when there was actually a significant difference in CPU performance given the chạy thử profile.

nguồn Consumption

Power consumption is a top concern for hardware manufacturers. We test using an Extech 380803 True RMS power analyzer. It is a really nice unit that even records usage over time.

Intel Core i7-4770 Power Consumption

This certainly shows Haswell is doing well but not that much better than previous generation CPUs. Especially in terms of idle power consumption. Of course, faster speeds mean workloads are done faster & more time at idle. On the other h&, this was not a major breakthrough on the desktop. On the sản phẩm điện thoại side, the reduction in on-board power components and idle power consumption is a big giảm giá. The Hãng Intel Core i7-4770 is a solid performer in terms of tốc độ and power consumption. Since the Intel Xeon E3-1200 V3 series will giới thiệu this architecture, a sub-20w idle architecture is a major breakthrough for racks of servers. We will see more on this in the coming days.

Conclusion

Overall, Haswell does provide a nice IPC bump as compared to lớn Ivy Bridge. The big question at this point is, what about the Hãng Intel bộ vi xử lý Core i7-4770 versus older hardware? If one has an Intel Core i7-2600K or Intel Vi xử lý Core i7-3770K this is probably not a worthwhile upgrade. There is a new chipmix & socket involved. For that matter, if one is looking khổng lồ nâng cấp a Sandy Bridge generation computer, used Ivy Bridge processors may be a better value at this point. At best, the Hãng Intel HD 4600 graphics are a slight nâng cấp over what Ivy Bridge had & processor speeds are again a slight nâng cấp. For those users with socket LGA1156 parts, Haswell may indeed be a solid nâng cấp option. The inclusion of technology lượt thích VT-d, TSX and etc in the Hãng Intel Core i7-4770 versus the Intel bộ vi xử lý Core i7-4770K may make it a solid choice for many users that vì chưng not overcloông xã. Generally, the non-K parts are a bit less expensive sầu so if features và cost savings are more important than overclocking (3.4GHz is also very fast) then the Hãng sản xuất Intel bộ vi xử lý Core i7-4770 is a better buy.

One area to lớn investigate is how the higher TDP parts impact power consumption. On one hand, there are fewer components. On the other hand, the higher TDPhường. Haswell chips need lớn be actively cooled. That means that some of the benefit may be negated by increased tín đồ tốc độ if the heat needs to be dissipated by the CPU fan versus passively cooled VRM stages. Consider that a follow up. Of course, more in store this week with Haswell, the Hãng Intel Vi xử lý Core i7-4770 & Intel Xeon E3-1200 V3 processors. Stay tuned!
