Product Brief Intel® Xeon® Processor E3-1200 Family

What is in Your Workstation? Why choose Intel® Xeon® processor E3-based workstations versus Intel® Core™ i3, Intel® Core™ i5 and Intel® Core™ i7 processor-based desktops Intel® Xeon® processor-based workstations represent the premier platform used by industry innovators to create, test and modify their ideas. If a user can accelerate an evaluation of an idea by as little 20% per day (1.6 hours), they can potentially reduce the design cycle time by almost one business quarter. This paper explores key elements and differences that exist between an entry-level workstation based on the Intel® Xeon® processor E3- 1200 family and desktop systems based on Intel® Core™ i3, Intel® Core™ i5, and Intel® Core™ i7 processors. We will contrast each platform on four key workstation pillars; processor performance, cache size, memory type/speed and graphics. Where They Are Similar Entry-level workstation solutions based on the Intel Xeon processor E3-1200 family and business clients based on Intel Core i3/i5/i7 pro- cessors have a foundation based on 32nm Intel® microarchitecture code named Sandy Bridge. They both support a variety of computa- tional core counts and varying sizes in Last Level Cache (LLC), Intel® Advanced Vector extensions, and SATA 3.0. Where They Are Different It is important to understand that delivered performance is not just about frequency or the number of cores, it is also about the entire infrastructure that helps get data to where it is needed, when is it is needed, so that it can be transformed into actionable information in the shortest amount of time. Computational Cores • Intel Core i3 processor supports a high clock frequency (up to † 3.3 GHz) and Intel® Hyper-Threading Technology (Intel® HT Tech- nology). However, it is limited to only 2 physical computational ◊ cores and does not support Intel® Turbo Boost Technology. Δ A 3.3 GHz Intel Xeon processor E3-1245 with an 8M LLC supports Intel Turbo Boost Technology and delivers up to 2X better perf- 1 ormance than an Intel Core i3 processor-based business client. • Intel Core i5 processor supports up to 4 computational cores, supports Intel Turbo Boost Technology, but does not feature Intel HT Technology. The support for Intel Turbo Boost Technology accel- erates single-threaded applications like CAD, but add-on applications that support opportunities like digital prototyping, rendering and ray-tracing options will have limited upside performance potential. A 3.3 GHz Intel Xeon processor E3-1245 with Intel HT Technology 2 turned on can deliver up to 25% better performance. • Intel Core i7 processor supports 4 cores, fast frequencies, Intel Turbo Boost Technology and Intel HT Technology. It is similar to the Intel Xeon processor E3-1200 family but trails in graphics performance and the availability of ECC memory. • Intel Xeon processor E3-1200 family supports 4 cores and also supports the fastest available frequency (3.5 GHz Intel Xeon processor E3-1280), Intel Turbo Boost Technology, and Intel HT Technology. It is similar to the Intel Core i7 processor, but supports accelerated graphics performance for professional applications, called Intel® § HD Graphics P3000 (available with Read the full Product Brief Intel® Xeon® Processor E3-1200 Family.
