HP Workstations FAQs

FAQ | HP Desktop Workstation FAQs
Does the end-user have to recompile the applications to see the performance advantages of the new Intel® Xeon®
processors?
• New Intel® Xeon® processors are designed for immediate application performance increases due to new processor
and memory architecture.
What are the benets of multi-core processors?
• Intel® multi-core processors
1
provide greater processing resources. Multi-core processors are ideal for usage
models requiring multi-tasking (running many applications or simulations at once); working on spread sheets
 whilelisteningtomusicwithviruscheckersandsystembackupsrunning(poweroce);orusingapplications 
that can split a task across processors (multi-threaded), like animation/rendering in Digital Content Creation.
What do these terms mean?
Dual-socket Two physical CPU sockets
Dual-core Each CPU package has exactly two processor cores
Quad-core Each CPU package has exactly four processor cores
Six-core Each CPU package has exactly six processor cores
Eight-core Each CPU package has exactly eight processors cores
Multi-core Each CPU package has multiple (2, 4, 6…) processors cores
Dual-processor A system with two processors in two sockets
What is Intel® Turbo Boost 2.0 technology?
• Intel® Turbo Boost Technology 2.0
7
is a way to automatically run the processor core faster than the marked
 frequencyifthepartisoperatingunderpower,temperature,andcurrentspecicationslimitsoftheThermalDesign
Power (TDP). This results in increased performance of both single and multi-threaded applications.
How much faster will the processor run with Intel® Turbo Boost 2.0 technology?
• The maximum frequency of Intel® Turbo Boost Technology 2.0
1,7
is dependent on the number of active cores.
The amount of time the processor spends in the Intel® Turbo Boost Technology 2.0 state depends on the workload
and operating environment. Any of the following can set the upper limit of Intel® Turbo Boost Technology 2.0 on a
given workload:
• Number of active cores
• Estimated current consumption
• Estimated power consumption
• Processor temperature
• When the processor is operating below these limits and the user’s workload demands additional performance, the
processor frequency will dynamically increase until the upper limit of frequency is reached. Intel® Turbo
Boost Technology 2.0 has multiple algorithms operating in parallel to manage current, power, and temperature
 tomaximizeperformanceandenergyeciency.Note:Intel®TurboBoostTechnology2.0allowstheprocessor 
to operate at a power level that is higher than its rated upper power limit (TDP) for short durations to maximize
performance.
• As an independent and complementary feature, Intel® Hyper-Threading Technology
8
(Intel® HT Technology)
increases performance of both multi-threaded and single threaded workloads.
What memory does the HP Zx40 oer?
• HP Zx40 Workstations will only support 4th generation double data rate memory called DDR4.
Are there still 4 memory channels in this architecture?
• Yes, there are 4 memory channels for each CPU.

How much performance boost is expected with the new processors?
• The performance seen by a user will vary depending on the application and usage model.
