i'm interested is how it stacks up against the
thoroughbred xp and applebred duron...
and how overclockable is it?

Add me to the list. I just saw these pop up at NewEgg this week never heard of them before. Is AMD doing some spring cleaning of the warehouse?

Semptron is a new budget CPU family, with 2 different cores.

Semptron up to 3000+ = relabled Athlon XP with higher price tag, fits in socket-A.
Semptron 3100+ = Athlon64 with 256kb and 64bit extensions disabled, fits in socket754.

Semptron is just a NEW name for DURON. The so called "Celery" for AMD.

This is incorrect.

Duron only has 64kb L2 cache and a maximum 133MHz FSB where Semptron Socket-A has 256kb L2 cache and 166MHz FSB.

But like you said: it is the Celeron (=budget) CPU answer from AMD.

The AMD Sempron™ processor model 10 with 256K of L2 cache, the new value brand for every-day computing = replaces Duron model. Using QuantiSpeed™ architecture, and it is compatible with various operating systems including Linux and all existing Windows® operating systems.The AMD Sempron™ processor model 10 with 256K of L2 cache, based on proven 0.13 micron technology. The processor delivers excellent performance and low power, while maximizing system value and maintaining the stable and compatible Socket A infrastructure of the AMD Sempron processor. The 4-digit model(+) numbering system helps identify overall software performance—the higher the number the better the performance. Detailed technical documentation and performance benchmarks are available at www.amd.com.

The AMD Sempron processor model 10 with 256K of L2 cache is binary-compatible with existing x86 software and backwards compatible with applications optimized for MMXâ„¢, SSE, and 3DNow!â„¢ technology. Using a data format and single-instruction multiple-data (SIMD) operation based on the MMX instruction model, the AMD Sempron processor model 10 can produce as many as four, 32-bit, single-precision floating-point results per clock cycle.

The AMD Sempron processor model 10 with 256K of L2 cache features a seventh-generation microarchitecture with an integrated, exclusive L2 cache, which supports the growing processor and system bandwidth requirements of emerging software, graphics, I/O, and memory technologies. The high-speed execution core of the AMD Sempron processor model 10 includes multiple x86 instruction decoders, a dual-ported 128-Kbyte split level-one (L1) cache, an exclusive 256-Kbyte L2 cache, three independent integer pipelines, three address calculation pipelines, and a superscalar, pipelined, out-of-order, three-way floating-point engine. The floating-point engine is capable of delivering top-of-the-class performance on numerically complex applications. The AMD Sempron processor model 10 with 256K of L2 cache also includes QuantiSpeedâ„¢ architecture, a 333-MHz, 2.7-Gigabyte per second AMD Athlonâ„¢ system bus, and 3DNow! Professional technology. The AMD Athlon system bus combines the latest technological advances, such as point-to-point topology, source-synchronous packet-based transfers, and low-voltage signaling to provide an extremely powerful, scalable bus for an x86 processor.
The following design features summarize the QuantiSpeedarchitecture of the AMD Sempron processor model 10 with 256K of L2 cache: A nine-issue, superpipelined, superscalar x86 processor microarchitecture designed for increased instructions per cycle (IPC) and high clock frequencies Pipelined floating-point unit that executes all x87 (floating-point), MMX, SSE and 3DNow! instructions Hardware data pre-fetch that increases and optimizes performance on high-end software applications utilizing high-bandwidth system capabilities Advanced two-level translation look-aside buffer (TLB) structures for both enhanced data and instruction address translation. The AMD Sempron processor model 10 with QuantiSpeed architecture incorporates three TLB optimizations: the L1 DTLB increases from 32 to 40 entries, the L2 ITLB and L2 DTLB both use exclusive architecture, and the TLB entries can be speculatively loaded.The AMD Sempron processor model 10 delivers excellent system performance in a cost-effective, industry-standard form factor. The AMD Sempron processor model 10 is compatible with motherboards based on Socket A.

from what i've read in the trade mags, it is a thorton core juiced to a 333 bus from the 266 bus...

lets say you have a athlon 2400xp running at 2.00ghz with 266fsb..and the
sempron 2800 running at 2.00ghz with 333fsb...
is the only factor in wu times a higher fsb?

Semptron uses the Thouroughbred-B core. Thorton is a Barton core with half the cache disabled, thus much more expensive to produce.
Semptron runs of a 166MHz-DDR (333MHz) FSB, but there are also Athlon XP's that run of a 166MHz-DDR FSB, so nothing new here.

With a higher FSB, memory troughput is higher, so it helps reduce WU time (though not much).

so better off to stay with the less expensive
Duron 1800 and athlon 2400xp.
not enough difference in bang for the $$$$!

Athlon XP 2400+ with the "Barton" core has 512k L2 and will process a WU faster. That FSB bump is not enough to overcome the bigger L2 in my experience.
