Review: 3 laptops powered by Intel’s Core i7 processor
Testing how well Intel’s Core i7 mobile processors can move your multimedia
By Brian Nadel
Intel Corp.’s new Core i7 family of processors includes the company’s most advanced mobile chips. First introduced in September 2009, the design was revamped this January. The latest version of the mobile Core i7, called Arrandale during its development, is built on a 32-nanometer fabrication process and offers base speeds that range from 1.06 GHz to 2.66 GHz.
Systems equipped with the new Core i7 can deliver between two and three times the performance of a Core 2 Duo notebook. In other words, these processors and the systems built around them are meant for users who demand high performance — and are willing to pay for it. For example, the Core i7 Extreme Edition lists for a bulk price of $1,054, whereas the Core 2 Duo processors can cost up to $619 but tend to hover more in the $300 range.
To see if the Core i7 family lives up to its billing, I gathered three new notebooks for a high-performance shootout: Fujitsu’s LifeBook E780, Hewlett-Packard’s EliteBook 8540w and Lenovo’s ThinkPad W510.
Intel’s new processors contain 774 million transistors shuttling data back and forth on a sliver of silicon the size of a pinky nail. (In contrast, the Mobile Core 2 Duo and Atom processors found in mainstream notebooks and netbooks have up to 291 million and 47 million transistors, respectively. )
Core i7 processors come with either two or four processing cores, depending on the model (the Core 2 Duo comes with two while the Atom comes with one). Equipped with Intel’s Hyper-Threading technology, each core can handle two streams of calculations. This lets the processor do four — or eight — tasks at once, a capability that is particularly useful when running repetitive calculations, such as in a complex spreadsheet.
Most processors stay at their set clock speed while working, but Core i7 processors can speed up for brief periods to handle particularly intense work. Called TurboBoost by Intel, this process helps the processor act like a marathoner and sprinter in one. For example, the 620M model runs at 2.66 GHz, but will speed up to 3.33 GHz if the operating system senses it needs more processing power and the chip is not overheating. As soon as it gets too hot or the computing load decreases, the chip drops back to its normal speed. It’s all automatic and invisible to the user, but it means higher performance when necessary.
A critical element of the Core i7’s performance is its ability to cache frequently used data and instructions within memory cells; these cells are close to the processing cores, which streamlines the processor’s operation. The chip provides 64KB of Level 1 and 256KB of Level 2 cache as well as 4MB to 8MB of Level 3 cache, depending on the model. The result is that the processor spends less time waiting for data and instructions and more time working.
All this hardware has a dark side: It needs power. According to Intel representatives, while there is some spread based on the amount of cache and clock speed, the Core i7 920XM tends to use 65 watts of power. In comparison, a midrange Core 2 Duo uses about 22 watts and an Atom uses about 5 watts.
This not only drains a battery quicker than you can say «Where’s the closest outlet?» but requires extra cooling from a fan or two to prevent overheating, further cutting into battery life. As a result, most Core i7-equipped notebooks also have six- to nine-cell batteries.
In addition, Core i7 laptops tend to be among the most expensive around. That’s true in part because they’re also among the best equipped; they’re meant for those looking for heavy-duty multimedia machines for work or play. As a result, these systems can cost anywhere from about $1,500 to over $3,000, depending on what options you go for.
But you will get a significant performance boost. Even the slowest of the three Core i7 machines I tested — the Fujitsu LifeBook E780 — ran 63% faster in my tests than a Lenovo IdeaPad Y450 with a 2.53-GHz Core 2 Duo processor.
Buyers who are just looking for a competent system can get what they need for a lot less. But if you’re buzzing through complex spreadsheets, editing high-definition video, streaming an HD movie or working with a 3D CAD model, a full-size notebook with a Core i7 processor is often the best tool for the job.

While the new 16-core Intel Alder Lake-HX mobile processors for portable workstations and high-end gaming laptops have only been unveiled recently, Chinese publications are already starting to publish their reviews. For example, the team of the Chinese platform Golden Pig Upgrade Pack published a review of the Core i7-12800HX chip.

According to Intel, the Alder Lake-HX series combines processors designed with the same semiconductor dies as desktop Alder Lake-S, but optimized for power consumption and moved to a BGA package. The mobile Alder Lake-HX has one more aspect in common with the desktop ones. They require a separate HM670 chipset on the laptop motherboard, unlike the same mobile Alder Lake-P, in which the chipset is built into a separate die located on the same substrate as the processor core die.
Alder Lake-HX chips support 16 PCIe 5.0 lanes for graphics card connection and 4 PCIe 4.0 lanes for NVMe SSD. Support for an additional 16 PCIe 4.0 lanes and 12 PCIe 3.0 lanes is provided by the chipset. The presence of the Intel HM670 chipset can be noted in the photo below (a compact microcircuit circled in red), where the NVIDIA GN20-E6 GPU, the basis of the mobile GeForce RTX 3070 Ti, also flaunts. On the right side of the picture is the Core i7-12800HX.

There is also a difference between mobile BGA and desktop LGA chips. The first one is 2.2 mm thinner than the desktop version. Some SMD components of the mobile version of the chip have been moved to another location on the substrate. However, the crystal itself with the computing cores is located in the same place, in the center.

A Chinese reviewer got two identical Lenovo Y9000P gaming laptops equipped with GeForce RTX 3070 Ti graphics accelerators, as well as the same amount of DDR5-4800 RAM. The difference between laptops is only in processors. One uses a 14-core Core i7-12700H (Alder Lake-P), the other uses a 16-core Core i7-12800HX (Alder Lake-HX). The PL1 and PL2 power consumption limits for the Alder Lake-P chip are 115 and 135 W, while the Alder Lake-HX model is increased to 125 and 175 W, respectively.
The Core i7-12800HX offers almost the same single-thread performance as the Core i7-12700H. However, its multi-threaded performance is 15% higher on average.

In games, the presence of two additional cores and 100 MHz of additional maximum clock speed, which is 4. 8 GHz in the Alder Lake-HX model, does not matter.

Both processors demonstrate approximately the same level of performance. The difference in favor of the Core i7-12800HX is only 2.56%, and even then, only in some AAA projects.

The UserBenchmark synthetic test database has an entry about testing an unreleased mobile Intel Core i7-12650HX processor, allegedly related to the mobile part of the Alder Lake-S series. Recall that to date, Intel has released a similar processor Core i7-12650H of the Alder Lake-P series.

The latest rumors say that Intel is going to expand the series of mobile chips with analogs of desktop processors, but in a BGA package. These processor dies contain 8 high-performance P-cores and 8 energy-efficient E-cores, while the already presented Alder Lake-P series models use dies with a maximum configuration of 6P + 8E cores.
Image Source: UserBenchmark
The UserBenchmark database entry indicates that the Core i7-12650HX does not have the same core configuration as the Core i7-12650H, further segmenting Intel’s mobile processor lineup and likely causing more confusion among buyers. The Core i7-12650HX itself contains 14 cores and supports 20 threads. This assumes the use of a stripped-down 6P+8E core configuration.

It should be recalled that last year Intel’s slide hit the Web, which indicated a certain series of H55 processors with a TDP range of 45 to 55 watts.
Image source: VideoCardz
Presumably, the H55 refers to the HX series of processors, the representative of which appeared in the UserBenchmark synthetic test database. However, it should also be pointed out that the slide does not contain configuration information for the 6P+8E cores within the H55 series.

Intel itself has yet to comment on the potential launch of the Alder Lake-HX processor series. However, according to the portal VideoCardz , gaming laptops based on these chips are already being developed.

According to the publication, Intel plans to release at least two Alder Lake-HX series processors.
