Intel Turbo-boost Force to Max

Xeon E v3-v4 base and turbo speeds Discussion in ' Processors and Motherboards ' started by joekApr 2, Joined: Mar 20, Messages: 27 Likes Received: 9. In search of a CPU with goood performance at lower active core counts, but with enough cores to spread around for a virtualized environment and still be affordable led me to a closer look at the turbo speeds. One thing led to another the "search" got a bit out of handand I ended up with the eye chart below. My takeaway is that base clock speeds are no longer a good indicator, or at least a sufficient indicator, when comparing CPU's. The turbo speeds and capability of these CPU's must be considered to obtain a complete picture and and tells a more interesting story. In particular, the E v4 appears to have significantly more headroom than v3. The v4's turbo-binning is also a bit more granular than V3 not shown in the chart. Apologies in advance for any errors; it's a bit of a slog to collect-collate-verify information from various sources. Corrections-suggestions appreciated; thanks in advance. Nominal precedence of sources for information in table if it wasn't in the first source, try the second, if it wasn't there Primary source is Intel official prices list; italics indicates source is Intel press material or ARK. NOTE: No turbo-boost details are available; assumption is that max active cores, the per-core frequency and total clocks is directly related to the base frequency. Not necessarily a valid assumption as can be seen from other processorsso take with a grain of salt until-if detailed turbo-boost information is available for these CPUs.

I always found that one of the biggest differences between the generations of i7s is how flexible the turbo mode is and how fast it kicks in. The step was particularly notable when running things like shellscripts on Sandy Bridge and then Ivy Bridge. Ivy bridge runs away big time if turbo is on, even for same base and same turbo multiplier. So just keeping going in turbo. Ivy did that a lot better. JorgeAtSalk and Ramos like this. At first glance, the Ev4 with a drop of 0. Pretty much the same with the L, and that 1.

You can search our catalog of processors, chipsets, kits, SSDs, server products and more in several ways. Brand Name: Core i7. Product Number: iU. Code Name: Kaby Lake. Lithography refers to the semiconductor technology used to manufacture an integrated circuit, and is reported in nanometer nmindicative of the size of features built on the semiconductor. Use conditions are the environmental and operating conditions derived from the context of system use. Cores is a hardware term that describes the number of independent central processing units in a single computing component die or chip. A Thread, or thread of execution, is a software term for the basic ordered sequence of instructions that can be passed through or processed by a single CPU core. Processor Base Frequency describes the rate at which the processor's transistors open and close. The processor base frequency is the operating point where TDP is defined. Frequency is typically measured in gigahertz GHzor billion cycles per second. CPU Cache is an area of fast memory located on the processor. Thermal Design Power TDP represents the average power, in watts, the processor dissipates when operating at Base Frequency with all cores active under an Intel-defined, high-complexity workload. Refer to Datasheet for thermal solution requirements. Embedded Options Available indicates products that offer extended purchase availability for intelligent systems and embedded solutions. See your Intel representative for details. Find products with Embedded Options Available. The number of memory channels refers to the bandwidth operation for real world application. ECC memory is a type of system memory that can detect and correct common kinds of internal data corruption. Note that ECC memory support requires both processor and chipset support. PCI Express Revision is the version supported by the processor. Peripheral Component Interconnect Express or PCIe is a high-speed serial computer expansion bus standard for attaching hardware devices to a computer. The different PCI Express versions support different data rates. USB Universal Serial Bus is an industry standard connection technology for attaching peripheral devices to a computer. SATA Serial Advanced Technology Attachment is a high speed standard for connecting storage devices such as hard disk drives and optical drives to a motherboard. The socket is the component that provides the mechanical and electrical connections between the processor and motherboard.
