Is it necessary to upgrade from Sempron 2500 to Athlon 2800?

Athlon: AMD high-end processor, divided into 754-pin and 939-pin, 754-pin memory controller single-channel, 939 integrated dual-channel controller. L2 cache 512k.

Sempron: AMD low-end processor, 754-pin, built-in single-channel memory controller, L2 cache 256K or 128K

It is strongly recommended that you do not change, in addition to their main frequency, there is also a different secondary cache, the athlon is larger than the flash dragon, and the same 2800+ u their speed is almost the same.

It's easy for you to go over 2500+ to 2800+, there's no need to buy another one.

Now that the CPU is so cheap, I recommend you change it to 3600+ (dual-core) or 3800+ (dual-core)!!

If your motherboard doesn't support dual-core, it's not bad to switch it to a single-core 3500+, but there's not much difference between the 2500 and the 2800!!

Not much stronger. Dual-core Athlon 3600+ is recommended

Upgrading doesn't bring much performance improvement, so it's better to just change the CPU

I'm dizzy. When you upgrade, you need to see if the interface is the same.

It's not going anywhere, it's better to add memory directly.

Yes, it's better not to change it, and you want to change it directly.

The same type of CPU, the low frequency is better, like the previous AthlonXP1700+, XP2500+, Celeron A300, Celeron and so on are all like this, and the current SEPRON 2500+ and P4 506 and Celeron D331 are all better processors. The 2800+ overclocking performance is slightly worse.

That's right, because the external frequency of 2800+ itself is relatively high, so it is not as good as the 2500+, which has a relatively low external frequency.

Indeed it is! Sempron 2500+ is currently the most cost-effective CPU! Overclocked to match 3000+!The overclocking performance of the Sempron 2800+ is not as good as that of the 2500+

This thing is not absolute

The main frequency is not the same as the L2 cache.

The clock frequency inside the CPU is the operating frequency of the CPU when it performs operations. Generally speaking, the higher the clock speed, the more instructions can be completed in a clock cycle, and the faster the CPU will operate. However, due to the different internal structures, not all CPUs with the same clock frequency have the same performance.

Cache

Most of the data information processed by the CPU is retrieved from memory, but the computing speed of the CPU is much faster than that of memory, so a memory is placed in this transmission process to store the data and instructions that the CPU often uses. This increases the data transfer speed. There are two types of caches.

L1 cache. i.e. l1 cache. It is integrated inside the CPU and is used for the temporary storage of data during the processing of data by the CPU. Since the cache instructions and data work at the same frequency as the CPU, the larger the L1 cache capacity, the more information can be stored, which can reduce the number of data exchanges between the CPU and the memory and improve the computing efficiency of the CPU.

However, because the cache memory is composed of static RAM and the structure is complex, the capacity of L1 cache cannot be too large in the limited CPU chip area.

L2 caching. i.e. l2 cache. Due to the limitation of L1 cache capacity, in order to increase the computing speed of the CPU again, a high-speed memory, that is, a L2 cache, is placed outside the CPU. The main frequency is flexible, and can be the same frequency as the CPU, or it can be different.

When the CPU reads data, it looks first in L1, then from L2, then in memory, and then in external memory. Therefore, the impact of L2 on the system cannot be ignored.

2500+ Frequency: , L2 Cache: 256k

2600+ Frequency: , L2 Cache: 128k

2800+ Frequency: 256k

2500 (, 256k cache), 2600 (, 128k cache), 2800 (, 256k cache).

BI, BO is 32 bits, and BX ends with 64 bits, don't forget!

Barton's performance is better Level 2 cache is larger than 512 sempron2800+ is 754 bits of 64 bits, integrated memory is controlled in the CPU, but although Barton's is 32 bits, its overclocking performance is particularly good, it can be overclocked up to 3200+ and is very stable, and the temperature is only less than 50!! The flash dragon is not good, the second-level cache is only 256, except for 64, the others are very general, but the price is low.

In fact, it is almost the same, the main frequency is only between 200-300, and it is not good when the price is separated.

Just buy a 3000+ one.,It's mainly a kanban board.,So it's good to overclock.。。。

Each has its own strengths, Barton can supercharge, 64 Shining Dragon, I choose Shining Dragon, after all, 64 is the mainstream in the future.

The new Sempron is better, with a new architecture.

2800+ is better without overclocking. 2500+ can kill 2800+ in seconds after overclocking. The 2500+ is known as the king of AMD K8 series overclocking. But that's a long time ago.

- - The core is changeable.

Your 3800 is the host**, right? That's shabby, I don't recommend giving you a cost-effective 939 needles 3000+.

It is recommended that you buy a duron64 2500+ to guarantee more than 3200+, **cheap and sufficient.

No matter how good Athlon, there is still a bottleneck in the L2 cache, how can the L2 cache be too small, if you want to buy 939 needles, 3000+ expensive points, but it is worth it.

The best cost performance of Shanlong is, of course, 2500+, but it is rare to buy it.
