What is the difference between IBM R series and T series?

r is a replacement desktop model. Features: The body is wide and thick, the heat dissipation is good, the battery is durable, and the appearance is slightly uglier than that of the T series.

T belongs to the business type, the performance is relatively good, the battery is mediocre, and the appearance is good-looking.

The warranty is determined based on the service you purchased.

R is an ordinary machine, T is a high-end business machine... The motherboard is different, and the material of the shell is also different...

Analysis: Market positioning of the R series The R series, formerly known as the i series, is a model designed by IBM for the low-cost market, and the target group includes small and medium-sized enterprises, educational institutions and some home users with low operating costs.

Although the overall design of the R series is to apply the T series, in order to widen the gap between the R series and the T series, so as not to have too fierce competition between its own product lines, and at the same time to control the cost of the R series, the R series has been weakened and simplified in the following aspects compared with the T series.

1 .Simplified hardware configuration. Compare the hardware configuration of the R series and T series of the same era**, and you will find that the R series models are always a notch lower than the T series of the same period, especially when it comes to graphics cards.

2.Simplification of expansion ports. Compared with the T series of the same period, the R series has made some simplifications in the expansion port, taking the R40 as an example, it can be seen that the R40 has only one Type II PC card slot in the body of the same thickness as the T30 (and compatible with Type III PCMCIA devices).

IBM's intention in doing this is to widen the gap between the R series and the T series, and to avoid the cannibalism between "R" and "T".

3.Simplified materials and workmanship of the fuselage. Starting from R30, the top cover of the fuselage is made of engineering plastics, which is in line with the titanium used in the T series, if you can't see the grade gap at a glance :), you can experience the "civilian" identity of the R series by touching it.

4.Simplification of warranty and after-sales support. As IBM's top commercial model, the T series has a three-year international warranty qualification, while the R series is a little thinner in the warranty, except for a few top-level R40 with a 3-year international warranty, they can only enjoy a one-year international warranty.

In addition, the R series has received less support in terms of driver updates, taking the BIOS as an example, the R40 has only released 6 versions of BIOS update files for almost a year, while the T40 has already had 8 BIOS update ...... in just half a year

I don't know if the above explanation can satisfy you.

But there is no compromise in terms of performance.

Let's put it this way, intuitively.

There is not much difference in the quality between the R series and the T series.

The main reason is that they target different consumer groups.

The T-Series is aimed at the high-end group and is aimed at business people.

The R series is aimed at ordinary consumer groups.

The T series is both aesthetically pleasing and lightweight.

The R series is a bit bulky.

I've used both series.

Originally I used T43, now I use R61

There is no difference at all in performance and use.

It's when I take it on a business trip that I realize the difference.

It's that the current machine is much heavier than the previous T43.

In appearance, it is not as compact and beautiful as the T43.

That's the difference in my opinion.

The difference is significant, R is a cut corners version of T, with a lot of thickness.

The bar has been lowered in the choice of materials.

1.Both series were developed by IBM before Lenovo took over, and the main purpose of the R series at that time was to meet the low-price consumer group, and some changes were made in the design and manufacturing process of the machine, but there was no compromise in performance.

There is little difference between the quality of the series and the T series, mainly because the consumer groups they target are different, the T series is aimed at the high-end group, aimed at business people, while the R series is aimed at ordinary consumer groups, and the difference is determined by the product layout and market positioning.

The T series is both beautiful and lightweight, the R series is a bit bulky, the difference between the series and the R series is very small, the R series is very cost-effective, you can buy R, it is more affordable4At present, the T series and R series top cover materials are the same, all are carbon fiber composite materials, the substrate is Mitsubishi's polyester material, the current T series and R series internal structure layout is exactly the same, only a few parts are different, and most of the parts are common! There is a debate about whether the motherboards of T and R are exactly the same, but what can be known at present is that the BIOS of T can be used normally when flashed to R, and the design of the motherboard is actually basically the same.

The teardown proves that the 14-inch T-Series and R-Series have screen roll cages. The 15-inch R-Series is missing a screen roll cage.
